Brain-Computer Interface Translates Brain Signals Associated with Handwriting into Text | Computer Science, Neuroscience – Sci-News.com
Researchers with the BrainGate Collaboration have deciphered the brain activity associated with handwriting: working with a 65-year-old (at the time of the study) participant with paralysis who has sensors implanted in his brain, they used an algorithm to identify letters as he attempted to write them; then, the system displayed the text on a screen; by attempting handwriting, the participant typed 90 characters per minute more than double the previous record for typing with a brain-computer interface.
As part of the BrainGate clinical trial, researchers are using tiny electrode arrays to record signals from the motor cortex of the brain; those signals can then be used to control robotic prostheses, computers or other devices; the hope is that such a system may one help restore communication and movement in people with paralysis due to injury or illness.

Brain-computer interfaces can restore communication to people who have lost the ability to move or speak.
So far, a major focus of brain-computer interface research has been on restoring gross motor skills, such as reaching and grasping or point-and-click typing with a computer cursor.
However, rapid sequences of highly dexterous behaviors, such as handwriting or touch typing, might enable faster rates of communication.
Scientists from the BrainGate Collaboration have been working for several years on such systems.
Previous studies have involved trial participants thinking about the motions involved in pointing to and clicking letters on a virtual keyboard. That system enabled one participant to type 40 characters per minute, which was the previous record speed.
For the latest study, the BrainGate researchers wanted to find out if asking a participant to think about motions involved in writing letters and words by hand would be faster.
An important mission of our BrainGate Consortium research is to restore rapid, intuitive communication for people with severe speech or motor impairments, said Professor Leigh Hochberg, a critical care neurologist in the School of Engineering and Carney Institute for Brain Science at Brown University, the Center for Neurotechnology and Neurorecovery at Massachusetts General Hospital, and the Department of Veterans Affairs Providence Healthcare System.
The new demonstration of fast, accurate neural decoding of handwriting marks an exciting new chapter in the development of clinically useful neurotechnologies.
We want to find new ways of letting people communicate faster, said Dr. Frank Willett, a neuroscientist at Stanford University and the Howard Hughes Medical Institute.
This new system uses both the rich neural activity recorded by intracortical electrodes and the power of language models that, when applied to the neurally decoded letters, can create rapid and accurate text.
As part of the clinical trial, the scientists placed two tiny electrodes about the size of a baby aspirin in a part of the trial participants brain associated with the movement of his right arm and hand.
Using signals the sensors picked up from individual neurons when the man imagined writing, a machine learning algorithm recognized the patterns his brain produced with each letter.
With this system, the man could copy sentences and answer questions at a rate similar to that of someone the same age typing on a smartphone.
The system is so fast because each letter elicits a highly distinctive activity pattern, making it relatively easy for the algorithm to distinguish one from another, Dr. Willett said.
The innovation could, with further development, let people with paralysis rapidly type without using their hands, said Dr. Krishna Shenoy, a researcher at Stanford University.
This technology and others like it have the potential to help people with all sorts of disabilities, added Dr. Jose Carmena, a neural engineer at the University of California, Berkeley.
Though the findings are preliminary, its a big advancement in the field.
Brain-computer interfaces convert thought into action. This paper is a perfect example: the interface decodes the thought of writing and produces the action.
The people who enroll in the BrainGate trial are amazing, Professor Hochberg said.
Its their pioneering spirit that not only allows us to gain new insights into human brain function, but that leads to the creation of systems that will help other people with paralysis.
The teams work was published in the journal Nature.

Op-Ed | The 2020 ACM Turing Award is a step against diversity, equity and inclusion – The Stanford Daily
The Turing Award, dubbed the Nobel Prize of computing, is bestowed upon computer scientists who have demonstrated long-lasting impact and trend-setting technical achievements in computing, and is generally considered a lifetime achievement award. As such, the announcement of the award is a moment of celebration for the whole community. This was different for the 2020 award, announced in March 2021 by the Association for Computing Machinery (ACM) to be shared between Alfred Aho of Columbia University and Jeffrey Ullman of Stanford University.
Within hours of the awards announcement, social media was flooded with concerns by members of the computer science community over the selection. They recognized Jeffrey Ullman as an outspoken opponent of diversity, equity and inclusion over the past decades, arguing that the selection violates ACMs own commitment to diversity and inclusion, listed as one of the four core values of the organization, as well as its declared mission of promoting the highest professional and ethical standards.
The significance of the social and ethical implications of the Turing Award is heightened by the fact that it commemorates the legacy of Alan Turing, who pioneered modern computer science, helped end World War II and faced a great deal of discrimination in his tragic life before dying by suicide. Posthumously, he received an apology from the British Prime Minister and a royal pardon by Queen Elizabeth II.
Soon, many congratulatory notes to Ullman were taken back. Some of the leading figures in the community, including Shafi Goldwasser (past Turing Award laureate and member of the Turing Award committee) expressed concerns in solidarity with the victims of Ullmans discriminatory behavior, joined by others including the Turing Award committee Chair Olga Sorkine-Hornung and Yann LeCun, a recent laureate of the award. Within days, an open letter condemning the selection emerged that quickly amassed over a thousand signatures, including by such influential scientists as fellows of ACM, MacArthur fellows and laureates of the Nevanlinna Prize, Abel Prize and Turing Award itself.
Like many of my peers, I learned much of computer science from Aho and Ullmans excellent textbooks. In fact, the educational contributions of the duo in the form of their textbooks has been included in their award citation. Senior undergraduates at Sharif University in Iran, where I studied, often apply to graduate programs abroad. For us, the leaders in computing were the names on our textbooks, such as Knuth, Sipser, Hopcroft, Aho and Ullman. We thought of them as influential educators, people to look up to and people to seek advice from. Some of us contacted Ullman, and he actually did respond. His words were, however, nothing about graduate school or computer science. They were rants of hate and bigotry against Iranians.
In the mid 2000s, tired of having to respond to emails from Iranians every few weeks, Ullman set up his infamous Answers to All Questions Iranian webpage, which he maintained until late 2020. In this page, he records his views against Iranians and other groups, such as Native Americans. Despite this, he continued to correspond with Iranian students. One such correspondence (as detailed in the above-mentioned open letter) was made public in 2011, causing public outrage and a complaint to Stanford by the National Iranian American Council. In response, according to The Stanford Daily, Stanford dismissed the allegations, saying that there is no plan to discipline Ullman for his statements. In contrast, in 2003, the University of Oxford suspended a professor for sending one email of such nature to a student.
Ullman maintains that Iranian students who are in Iran or have grown up in Iran past the 1979 revolution should not be educated in the US and calls for a blanket ban on admitting them to US schools. He has set a personal policy of wanting nothing to do with them: He wont work with them and he wont advise them, solely based on their national origin. He has also expressed a similar assertion regarding Chinese students, in a Google+ post in 2015 as well as in private correspondence as recently as 2020, though it is unclear if he has gone as far as declaring a ban on that group.
There is no question that Ullman is entitled to his opinions. However, when he turns those opinions to actions and policies against students, a red line has been crossed. At Stanford, national or ethnic origin is an explicitly stated protected category in the universitys non-discrimination policy. Moreover, Stanfords commitment to diversity and inclusion, as stated in 2019, asserts to support all members of the community independent of cultural background, ethnicity, gender identity, or political affiliation. Stanfords Core Policy Statements (Section 4.2.2) considers exclusions for facultys conduct directly related to academic values in reference to the extent of their academic freedom.
Ullman and Stanford argue that he has no involvement in admissions. However, an outspoken and influential senior faculty (who has also chaired the department) can affect a departments climate as a whole. Moreover, in graduate admissions in nearly every US school, despite the existence of an admissions committee, selection is directly influenced by individual faculty members. As a crude heuristic, I looked over the list of 1,074 Ph.D. theses, as of this writing, done at Stanford Computer Science. Among the authors, I notice only 6 Iranian names, only one of whom has done an undergraduate degree in Iran. In contrast, Stanford Electrical Engineering lists 4,731 theses, and among those, I can identify about 176 Iranian names (the contrast gets sharper in recent decades). Of course, that might not prove anything for such a complex issue, but at least signifies a telling gap.
Regardless, for a faculty member to set a unilateral policy of discriminating against a group of students is already an action, one that goes against academic values that they have the duty to uphold. Furthermore, just being subject to Ullmans behavior could have been enough to deter young students from graduate studies altogether. Several computer scientists from Iran are now on the faculty at Stanford. The late Maryam Mirzakhani, a Stanford professor and the only woman so far to be awarded the Fields medal, completed her undergraduate studies in Iran. In Ullmans view, she should have been excluded.
Ullmans controversy is not about freedom of speech, nor politics. It is a purely academic one. It is not about separating the artist from the art. It is about the art itself. At a time when the computing community is struggling to broaden participation, Ullmans egregious actions are a disservice that goes against his own educational contributions for which he received a Turing Award. Factoring this into his overall academic impact, ACMs selection does not seem clear-cut anymore.
ACM first reacted to the controversy by tweeting that Ullmans statements do not reflect the views of ACM. In response to the open letter, ACM released a statement providing answers to precisely the two questions asked on the letter. Fourteen ACM Special Interest Groups released a separate statement expressing commitments to diversity and inclusivity. In summary, ACMs response is that the issue was missed since no complaint against Ullman had been on file with ACM, and that in future ACM will require nomination letters to indicate whether they are aware of any behavior inconsistent with ACM values. This is while ACM could have easily discovered the behavior by a simple web search, and of course nominators would have a conflict of interest to disclose any red flags.
While ACMs response is a positive step and promises long overdue reforms, it is far from sufficient. As time is now judging Stanfords dismissive reaction in 2011, which is partly responsible for todays controversy, it will judge any action ACM takes today. Ullman has had ample opportunity over the years to acknowledge harm and correct his behavior. Unfortunately, his April 2021 interview with San Jose Inside suggests otherwise, concluding that the conversation thus far hasnt swayed the professor.
I hope that, at the very least, ACM takes genuine and measurable steps to prove commitment to its stated values by impactful action and not just words. ACM should, foremost, recognize the damage done to the computing community and directly empathize with the victims of Ullmans actions, rather than strategizing to minimize the impact on the organization. Since Ullmans behavior is directly entangled with the educational impacts that contributed to the award, if ACM does not indeed share his views, the award citation and its public record should at least be amended with a disclaimer to reflect that. ACM should think of more effective reforms such as publicly announcing the nominees in advance and establishing clear mechanisms for rescinding awards in rare cases when relevant misconduct is discovered after the fact.
It is important to ensure that a clear precedent is set today by ACM that would not give a free pass to any future abusers of academic freedom. The computing community, which ACM aims to represent globally (as an international organization), needs to establish equal opportunity for everyone and ACMs selection this year has diminished much of the hard-earned progress. ACM needs to do better and bring back trust and hope to the community.

From insightful courses to traveling and teaching, reflecting on Penn’s ‘unending opportunities’ | Penn Today – Penn Today
Reflecting on her time at Penn, senior Hyacinthe Uwizera admits that she does have one regret: not heading downtown after the Eagles won the Super Bowl. I think it's the spirit of the people of Philadelphia, she says about the city shes called home for the past four years. I love that energy and that spirit.
Now, as the senior from Kigali, Rwanda, graduates from the School of Engineering and Applied Science, she is ready to take the skills shes gained from her major in computer science and minor in Africana studies to the next stage of her career. Shell also carry forward a number of memorable experiences gained from unending opportunities available at Penn.
Uwizera, who studied math, physics, and geography in high school, first became interested in engineering after working with Penn students on a solar-powered irrigation system in 2015. This project was part of the Rwanda Gashora program, a service learning initiative and collaborative program between her high school, the Gashora Girls Academy of Science and Technology, and Penn Engineering.After initially enrolling into Penns Electrical and Systems Engineering program, Uwizera later discovered a passion for computer science and decided to switch majors during her sophomore year. When I got here and got the taste of different majors, I took CIS 110, intro to computer science, and I realized that was what I was more interested in, she says. Math and critical thinking are few of the aspects of computer science that had me interested, and before you do a project you dont really have an idea of how to it. But as you start working on it, things start revealing themselves and you learn more as you work. Seeing the end product working is very rewarding.
While reflecting on her favorite computer science courses, Uwizera says that CIS 160 and CIS 121, taught by Rajiv Gandhi, were both memorable for her. CIS 160 is one of the hardest intro CIS classes, but I think its because of how he cared for every student that made me love the subject, stay focused, and do well, she says. Having someone that I looked up to believe in me and push me towards seeing that I can do it, that Im in the right place, helped me to know that I belonged in that field.
This past academic year, Uwizera was able to put all of her computer science skills to use as she completed her senior design project with a team of four students. Their app, Salon-IO, is designed to connect people who provide beauty services to new customers. Some students on campus know how to do braids, eyelashes, or nails, and others need those services, so we wanted something that connects people who dont have physical salons but provide services to people who are interested in those services, she says.
Outside of her computer science major, Uwizera also earned a minor in Africana studies. She initially took courses in this area because of her personal interest and says that completing a minor in this field has been nice to balance out her engineering coursework.
Uwizera says that shes thoroughly enjoyed all of her six Africana studies courses, from learning more about history through the War and Peace in Africa class to understanding the connections between different African language families. This spring, she took Music of Africa and enjoyed learning more about the music and artists she listened to while growing up. Its so interesting knowing where it comes from and how it influenced other places, she says.
In terms of favorites from Africana studies, she says the Fall 2018 Penn Global Seminar Seeing, Hearing, and Encountering South Africa was a highlight. This course looked at post-apartheid South Africa through the lens of history, politics, environment, art, and culture, and Uwizera got to travel to South Africa with her classmates during winter break. Its also the students in that class that made it an even better experience, she says.
Currently, Uwizera is working as a teaching assistant (TA) for CIS 550, one of the courses in the Master of Computer and Information Technology program. She says the experience rekindled her passion for teaching and tutoring and also helped her realize how much one can learn about a topic through teaching. You get to learn more, to see peoples different points of view, and theres the reward of knowing that you help someone, says Uwizera.
In addition to her academic coursework and time spent as a TA, Uwizera was also a member of the New Spirit of Penn gospel choir, the Society for African Internationals at Penn, a Penn World Scholar, and a Benjamin Franklin Scholar.
Before leaving for San Diego to start a new job at Intuit, Uwizera hopes to reconnect with other international friends while they are all still on campus, adding that its the people at Penn who have made these past four years memorable for her.
Another big takeaway from her Penn experience was the opportunity to travel before the pandemic, from working in Australia and Argentina during her freshman year to visiting South Africa her sophomore year. When I came to Penn it was my first time leaving my country, so in these past four years I realized how much I enjoy traveling and going to new places, she says.
Uwizera says that coming to Penn and getting a scholarship to study here completely turned my life 180 degrees from what she expected. And while there were certainly challenging parts of her University experience, theres one big positive that she will definitely take with her as she moves into the next stage of her career: the people, Philadelphia, and the unending opportunities that Ive gotten from Penn.

This virtual nurse can tell you a prayer and where to get a coronavirus vaccine – News@Northeastern
Clara is a healthcare provider who works with Black communities in Boston. Clad in a magenta blouse and a striped head scarf, she greets her patients by name and makes small talk before delving into questions about their diet and exercise. A small, framed cross is visible on the office wall behind hershes Christian herself and works predominantly with Black parishes around the city.
Clara isnt actually a person, though. Shes an animated virtual nurse developed by Timothy Bickmore, a computer science professor at Northeastern. Clara cant take vital signs or treat wounds, but she can make suggestions and help patients stay on track when it comes to general wellness matters, such as diet, exercise, and mental health.

Now, as COVID-19 vaccines become more accessible in Massachusetts, Clara will have a new jobto provide information about the vaccine to Black Bostonians, many of whom are distrustful of the vaccine, not least because of a long history in the United States of medical abuse and unethical clinical trials involving Black participants.
Theres a mistrust of the medical establishment based on generations of now-documented mistreatment of African Americans by doctors and the healthcare system in the United States, says David Wright, executive director of the The Black Ministerial Alliance of Greater Boston, a Christian community organization Bickmore partners with.
These vaccines were also created under an administration known for not telling the truth and using racist and xenophobic language, Wright says. Unsurprisingly, theres a mistrust of anything made under that administration.
For the past few years, Bickmore has worked with the alliance to promote spiritual and physical health throughout almost 30 Black parishes using his animated healthcare program. The vaccine project will be a continuation of this partnership.
We hope to provide information about where people can get vaccinated, and what they can expect, says Bickmore. We already have a relationship with the community, and they asked if we could help promote COVID-19 vaccines.
With funding from the National Institutes of Health, Bickmore and his team will launch the vaccine program within the next two months. New vaccine-related phrases will be added to Claras wordbank, and participants will be able to ask questions about the vaccine from the comfort of their own homes.
Even for individuals who dont have high computer literacy, the program is still easy to use, he says. Weve gotten great feedback. It seems to be working, and most people like it. Most of the time, theyre able to suspend their disbelief and really engage with the program.
Limited access to smartphones or computers could be an issue for some seniors, but overall, Wright doesnt think the technology aspect of the program will pose too much of a problem.
Id say a significant number of seniors regularly use smartphones, Wright says. I suspect the application will catch on as more and more people use it for church and community activities.
Bickmore and his team go to great lengths to tailor the program to the demographic of people they hope to help, in this case, Black Christians living in Boston. To build rapport, Clara incorporates Bible stories and spiritual language into the sessions.
The same way any good doctor would build trust with a patient, Clara shares personal information about herself with her patients and remembers things about their lives in order to build a social connection, Bickmore says.
The program is intended to last four years. In the coming years, if promoting the COVID-19 vaccine becomes a less-pressing issue, the team will also work on promoting influenza vaccines, another inoculation many Black people in the U.S. are hesitant to receive.
If you look at the literature, the most successful way to gain a patients trust is through face-to-face conversation, says Bickmore. Our animated counselor simulates just that, and shes actually particularly good at it.

Cal Poly seniors to launch second weather balloon into space with Project OWL – Mustang News
In 2019, aerospace senior Evan Agarwal teamed up with technology company Project OWL to test out a device that would provide cheap, limited Wi-Fi in disaster zones by launching it into space on a giant weather balloon and now they want to do it again.
The device, or payload, which they are calling a DuckLink is designed to be attached to a weather balloon and launched up to 100,000 feet into the upper atmosphere, reaching temperatures around minus 51 degrees Fahrenheit.
Following the initial launch, the Cal Poly team and Project OWL have wanted to do it again, but were halted with the start of the pandemic.
By the time we were about ready to say okay we kind of got all the pieces in place, you know, eight to 10 months later, COVID[-19] happens, Project OWL CEO Bryan Knouse said.
Since initially connecting with Agarwal, Project OWL has worked with two teams from computer science capstone courses, this years dubbing themselves the Quackheads team.
What started as a small team of about three to four Cal Poly students has become a dedicated group of 10 to 15, according to Knouse.
One of the big changes the team has made since the last launch, is transitioning from using off-the-shelf components largely from China, to making some of the electronics internally.
According to Knouse, the student team this year were able to build custom electronics for the device.
This is the first custom electronics board weve ever had, Knouse said. And weve been trying to do this for years and this computer engineering group is the first team that actually pulled it off.
By making the electronics in-house, Knouse said it can all be tailored to do exactly what needs to be done for their project that is, if they work.
The launch, which is tentatively set to happen May 14 and May 16 depending on weather patterns that week, is acting as a field test for some of these electronics.
For the Cal Poly team this is like the grand finale of their year-long effort designing this, Knouse said.
According to computer science senior and self-dubbed Quackhead Kevin Nottberg, who is in charge of hardware stuff and designing the board, he believes they were able to accomplish the task due to a global chip shortage.
When they were unable to outsource the parts they needed, the team was forced to make the electronics in-house. The team in the course a year prior was tasked with the same job, but unable to complete it.
Part of it I think was because the pandemic had shut a ton of stuff down with China, around end of February, March last year. So it totally screwed them over, but it actually helped us, Nottberg said.
The board, which the team calls the Quackerboard, took them approximately five weeks once they started building it and three revisions to get right.
According to Nottberg, the stakes were high if they were not able to get the board to work in time and they would not be able to test their electronics on the payload device.
Holy shit, this might actually turn out, Nottberg said when they finished it.
Computer science senior and fellow Quackhead Kevin Dixson has taken charge of the software aspect and writing all of the code that makes the board work.
Weve yet to make a board that didnt work, so props to Kevin [Nottberg] for that, Dixson said.
When it comes to the May launch, Dixson said a perfect launch would be if it all went off without a hitch.
If we never lose communication, and we know where it is the whole time, and it pops at 100,000 feet thats the ideal scenario, Dixson said.
According to Dixson, the balloon will go into the air for about a two-hour duration, during which time they should be able to communicate with the device. When the balloon pops, the team should get a notification and it should remain in contact while descending. Finally, the team should be able to locate the device and it should be in-tact, if all goes well.
And also we get cool pictures, Dixson said.
For Dixson, he said he has learned more doing this project than he has in any class he has ever taken at Cal Poly.
Thats kind of the best way to learn is just drop in the deep end and see if you swim, and I guess we swam, Dixson said.
Quackhead and a founding member of the project Agarwal said that what they are working on has the potential to impact a lot of people in a really positive way.
The team, along with Cal Poly and Project Owl, has won a contract with the U.S. Air Force that is currently being approved by the University and provides the team with the funding they need to get the project off the ground quite literally.
Right now, they are in a phase one contract, but if they can complete this technology demonstration, then they will receive a phase two contract and receive a lot more money, according to Dixson.
When asked why balloons? Agarwal said the balloons offer them an easy and effective way to test the range of their devices.
If we really want to stress test these things and say, lets keep going and going and going until we drop out, the best way for us to do that is just to go up, Agarwal said.
According to Nottberg, the payload devices could potentially be utilized as disaster relief networks, where they can build a network out of nowhere and provide connection where there might be hills or other forms of disruption in a provided area.
So its cool and really exciting to be working on something that actually has real positive potential, and that was kind of the same feeling we had last time and its grown a lot since then, Agarwal said.

Newswise A research team at the NYU Center for Cyber Security (CCS) at NYU Tandon are participating in a major initiative in collaboration with data security company Duality supported by a $14 million grant from the Defense Advanced Research Projects Agency (DARPA) to design a revolutionary new microchip (codenamed Trebuchet). The microprocessor, to be designed by CCS researchers Mihalis Maniatakos, research assistant professor of electrical and computer engineering; and Brandon Reagen, assistant professor of electrical and computer engineering and computer science and engineering, will accelerate and enable practical applications of an emerging type of encryption, called fully homomorphic encryption (FHE).
Typically, data encryption protects data in transit: its locked in an encrypted container for non-secure transit, then unlocked by the other party for analysis. But outsourcing to a third-party is inherently insecure. FHE is an advanced cryptographic technique, widely considered the holy grail of encryption, that enables multiple users to process encrypted data while the data or models remain encrypted, preserving data privacy throughout the analytics process.
The hardware Maniatakos and Reagen are developing as part of the 3.5 year project is of particular value to AI systems because it allows data scientists to train some of the most advanced machine learning (ML) models on encrypted data, enabling organizations to leverage greater amounts of diverse sensitive data for training.
With increased privacy concerns and tightening data protection regulations, organizations acrossindustries are looking for secure computing methods to train and execute AI models without exposing sensitive or confidential data, said Maniatakos.
FHE also secures outsourcing to a third party for processing, without that entity being able to unlock that data. One example of secure data outsourcing is the use of privacy-preserving machine learning, critical for such applications as personal DNA sequencing to scan for predisposition to some diseases.
FHE lets you encrypt your genome, send it to a service that predicts your predisposition to diseases, and you get the result back and decrypt it. The outsourced service cannot see your genome and cannot use it against you in any way, said Maniatakos.
Over the course of the project, Reagen will focus on hardware architecture, and Maniatakos the logic units for a feature called Large Arithmetic Word Sizes (LAWS) which can be used to accelerate FHE to practical speeds.
The Hardware to handle the numbers
The underlying mathematics behind FHE, developed in 2009, involve operations on polynomials of very high degrees (in the order of thousands) and with very big coefficients, requiring resource- and time-consuming computation. The solution lies in hardware that can natively process these very big numbers. Reagen, a computer architect who designs chips that can do very specific things to make them run much faster than general purpose hardware, is tasked with laying the groundwork for this chip.
To enable homomorphic encryption, my job is to take the building blocks of this unit not just memory, but a lot of parallel functionality as well as the LAWS units Mihalis is designing and customize, organize and allocate them on chip for a given area to maximize performance, which, at the end of the day, is the fundamental inhibitor of this encryption process. In fact, if performance were not an issue, everyone would be using FHE for the simple reason that you would never have to decrypt data. My job is to reclaim that performance.
Function-specific hardware (think of a graphics card, for example, or processing units designed for machine learning operations) is nothing new. For FHE, the key is in the bits a computer uses to represent numbers for the rapid calculations it performs. A typical processors architecture, organized for 32 bit operations, would take far too long and use too many resources to process the huge numbers required for FHE, explained Maniatakos.
You could do it, but it would be incredibly slow. It would be six orders of magnitude slower than unencrypted computation. Our task is to bring down the slowdown to maximum one order of magnitude.
At 32 bits, he explained, the largest number a chip can process is two to the power of 32 four billion which is fine for most applications. The problem is that with FHE the numbers processed are much bigger than 32 bits, in the order of thousands of bits and cant be represented natively, so computer has to split these numbers up, which incurs a lots of overhead.
Imagine we have a list of numbers, say one through 10, explained Reagen. Lets say that we first encrypt this data in such a way that this very small list of numbers turns into two lists where each element is 10 to 100 times as big. And suddenly, right off the bat, you increase the number size by a factor of 20 to 200. Now if you want to execute, say, multiplication functions on this bloated data you are not just going to be doing multiplication, you have to do many other functions that transform representations of the data. These meta-functions, in fact, take longer to run than the actual multiplication.
He added that designing customizations such as parallel hardware helps vastly increase computation speed by allowing multiple processes to happen at once at maximum throughput. Working as a team is important.
The key challenge in designing effective architectures is how to balance all of these processes and keep them fed with data, and collaboration with someone designing LAWS for the functional hardware units is critical to making sure performance is not left on the table.
The CCS team, in 2018, was actually the first to develop an early version of a homomorphic encryption chip that accelerated partial HE, allowing expression of a limited set of algorithms. This earlier version, making CCS the first to create a homomorphic encryption ASIC accelerator, allowed such applications as vote aggregation, and smart grid data applications.
For this project, the NYU Tandon team, after designing the chip, will hand the baton to collaborators at the University of Southern CaliforniaInformation Sciences Institute, Carnegie Mellon University, SpiralGen Inc.,Drexel University, and TwoSix Labs Inc. for integration, prototyping, fabrication and other processes.
The project at NYU Tandon will also fund four graduate students: Deepraj Soni, under the guidance of CCS Director Ramesh Karri; Homer Gamil, a research assistant under Maniatakos, who begins his Ph.D. work at NYU Tandon in September; and Karthik Garimella and Benjamin Heyman, doctoral and masters students, respectively, under Reagens guidance.

Inside the Economics of Science Papers – Walter Bradley Center for Natural and Artificial Intelligence
When a scholarly paper is published, someone has to pay.
Publishers like Institute of Electrical and Electronic Engineers (IEEE), my professional society, and Springer charge big bucks to read their papers. The fees are billed to individual subscribers and, more commonly, to companies and universities who want to give their employees access to the papers. My own university, Baylor, like most research universities, has a considerable library budgets on account of these publisher fees.
There is growing pressure to kill these fees in favor of open access to scholarly papers. Thus, anyone can read a scholarly paper at any time for free. Free access takes the money from the pockets of publishers so they push back. Someone has to pay, eventually, so open access, as it is called, means that the author bears the cost.
The author doesnt always bear the cost personally. Sometimes, the authors institution foots the bill. Cash cow organizations like Google readily pony up. In the U.S., if a public university coughs up the money for their employee author, the fees are paid indirectly either by the states taxpayers. When the fees are paid by government granting agencies like the NSF, NIH or NIST, they are paid by the US taxpayer.
MDPI, an open access publisher, charges authors between 1000 to 2000 Swiss Francs (over US$1000 to $2000) to publish in their open access journals.
Where do these fees go? At IEEE, paper authors, reviewers, and associate editors are not paid a dime. All is volunteer. When I was Editor-in-Chief of IEEE Transactions on Neural Networks, I was voted money to support one part-time clerical position but I personally received no compensation. A prevailing view is that the prestige of being an editor or author is payment enough. In academia in general, a major component in a professors promotion and pay raises is paper count. As the saying goes, the Dean cant read, but the Dean can count.
Professionally sponsored conferences also feed the cash-hungry publisher. I have been the Organizational Chair for numerous conferences, big and small. Volunteers from universities and companies run the conference but are paid nothing. The publications from these conferences are handed over to a publisher who then sells them.
There is an old joke that graduate students are machines that turn coffee into papers. Publishers take these papers and turn them into cash.
I am currently the Editor-in-Chief of the open-access journal BIO-Complexity and, yes, we have a publication fee. After thorough peer review, we have waived the fee for every paper thus far published in BIO-Complexity. Because the journal is small, we have been able to run it with all volunteers.
There are ways to avoid the publication cash grab described above. A popular tool is arXiv.org (pronounced archive where the X is pronounced like a k, as in the Greek chi. The site, managed by Cornell University, will post almost any scholarly work for free without peer review, at the request of an author. Someone, of course, reads it in advance, to be sure it is not whacko. But there is no peer review as such. Paper topics are physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics. I am aware of no bias in the acceptance of papers for arXiv, but in these days of blatant censorship by places like Amazon, YouTube, Twitter, and even Paypal, one never knows.
A second way to get hold of a paper for free is Google Scholar. Enter a topic like artificial intelligence ethics and you get a search of papers addressing the topic. To the right of many of these listings, you will find a link to a free copy of the paper. Many authors will also post copies of their papers on their own web sites. Google scrapes the web and then nicely links them here.
At one time, publication count was limited by paper supply. Each paper was typeset and printed, and a hard copy was sent to subscribers via snail mail. Printing runs were fixed. There was no print-on-demand. These physical constraints are all gone. Many conferences and journals no longer even generate hard copies. Everything is on line. Even older hard copy has been digitized and made available. For a price.
When web access became ubiquitous, publication count exploded. The graph of the IEEE publication count is revealing.1
Here are my speculations about the story this graph tells. Publication count increased linearly about 2500 papers per year until about 2000 when there is a sharp uptick. From 2001 to 2010, the increase was, on average, about 19,000 papers per year or roughly four times larger than before. The break point occurs when papers became available electronically. Without the requirement of hard copy publication, making a paper available became cheaper. When I came to Baylor from the University of Washington in 2003, the Baylor library had yet to subscribe to IEEE Xplore.
There is a dip in the curve for a few years, starting in 2010. I cant think of a reason why. But the upward trajectory starts again in 2014, breaking through 300,000 in 2019. Thats over a thousand papers every weekday. There was also a COVID dip in 2020 that is not shown on the graph.
Supply and demand pushes publication counts up and up. Academia rewards professors who publish and publishers are more than happy to accommodate the demand. For a price.
[1] Heres how I got the data. I went to IEEE Xplore and did a search year by year. IEEE, the Institute of Electrical and Electronic Engineers, subsumes electrical and electronic engineering and computer science. At over 400,000 members, IEEE is the worlds largest professional society. In Xplore, I entered the year 2000 and Xplore responded with 69,762 papers. This was repeated from 1980 to 2019. The search is not perfect but gives reasonable numbers.

Acting Secretary Joins Students, Teachers Across the State for Innovative Learning, Workforce Readiness Festival – Pennsylvania Pressroom
Harrisburg, PA - Continuing the commitment to STEM education and career advancement, Pennsylvania Department of Education (PDE) Acting Secretary Noe Ortega participated in the Remake Learning Days Across America (RLDAA) Festival, designed to provide students in kindergarten through high school with learning experiences to build their employability skills and prepare them for future careers. Over the course of eleven days, more than 600 events will take place in-person and virtually across the commonwealth. Preparing students for in-demand careers, especially in the growing fields of science and technology, is a priority for the Wolf Administration.
With event themesranging from planets to pixels to paleontology to pig farms and more, students across the commonwealth have a variety of unique opportunitiesto explore STEAM during Remake Learning Days, said Acting Secretary of Education Noe Ortega. This annual festival offers learning experiences that will help students strengthen their skillsets and prepare them for dynamic careers of the future.
Acting Secretary Ortega joined students virtually and offered remarks for the Ask the Patent Agent - PPG Scientist Series event. During the event, middle and high school students also heard from PPG Patent Agent Linda Anderson on her role as a patent agent, the importance of patents, and what skills are necessary for the career.
The RLDAA Festival is May 6-16 and focuses on providing numerous learning activities where students can express their creativity, increase their collaboration and critical thinking skills, and create connections between their educational experiences and their futures. PDEs Career Ready PA program has collaborated with organizers of this years RLDAA Festival to help elevate and increase awareness around employability skills and career readiness. This collaboration includes the Career Ready PA Backpack challenge, which provides students with opportunities to earn badges submit an artifact for their career portfolio. Remake Learning is a stakeholder in the Career Ready PA Coalition supported by the 10 Career Ready PA regional liaisons.
The Career Ready PA Backpack Challenge creates opportunities for students to obtain artifacts for their career portfolios by participating in Remake Learning Days events in school or at home. The Challenge connects learners to free, live community events offering hands-on learning opportunities that help build employability skills, such as collaboration, critical thinking, and teamwork, said PDEs Special Consultant to the Secretary for Career Readiness, Dr. Laura Fridirici. Students document their meaningful engagement in these events, which could include meeting a scientist or making their own invention, as they explore and learn more about the skills needed for a variety of careers.Students who participate earn a Career Ready PA Backpack Challenge digital badge. PDE will track participation in these events, and when a school earns 100 badges, theyll receive a banner recognizing this accomplishment.
This year, many of the programs offered to students are virtual, which creates and expands access opportunities for students while maintaining health and safety guidelines. Students can participate in the RLDAA events in their classrooms or individually at home. Pennsylvanias seven PBS stations have also joined the festival to provide media support, assist with promotions, increase access, and offer events.
The pursuit of artifacts is student-driven, very active and inquiry-based, and offer a deeper reflection on the skill sets needed in todays workforce which helps students understand how their academic learning is preparing them for adult life, said Remake Learning Director Tyler Samstag. Remake Learning Days allow organizations to open their doors so that young people can go into that environment and engage with people who use STEM skills and practice hands-on creating for a living.
For more information on Remake Learning Days Across America, visit their website.
The importance of STEM education has been strongly implemented in the Wolf Administration.
For Pennsylvania to perform as one of the nations leaders in STEM education, the Wolf Administration has dedicated several resources to the expansion. Recently, Governor Tom Wolf announced $10.8 million in PAsmart Advancing Grants to expand access to computer science and STEM education for Pennsylvania learners. Combined with PAsmart Targeted Grants announced in 2020, the Wolf administration has awarded nearly $20 million to bolster STEM and computer science (CS) in schools during the 2020-21 school year. Over the last three years, the Wolf Administration awarded 453 PAsmart grants to expand computer science classes and teacher training at over 765 schools across the commonwealth.
