The US and China as frontrunners in the battle for supremacy in the development of artificial intelligence (AI) may be leaving India some distance behind, but an Indian-born scientist is still considered one of the pioneers of research in the area. Dr Dabbala Rajagopal "Raj" Reddy, who celebrates his 86th birthday this month, is currently the Moza Bint Nasser University Professor in the Carnegie Mellon Universitys computer science department. His research interests include the study of human-computer interaction and artificial intelligence while his current research projects include spoken language systems; gigabit networks; universal digital libraries; and distance learning on demand".

Born in Katur, a small village in Andhra Pradesh with a population of 500 people who lived without water or electricity or doctors, Reddy learnt writing on sand since there was neither paper nor pencil. His father was a farmer and after going to the villages one-room primary school, the young boy became the first member of his family to attend college. After getting his bachelors degree from Guindy College of Engineering, Madras (now Chennai), and a masters degree from the University of New South Wales, Sydney, he worked for IBM in Australia for a few years before moving to the US for his masters degree followed by a doctorate, both in computer science, from Stanford University. Three years of teaching at Stanford was followed by a move to Carnegie Mellon University, where he founded the schools Robotics Institute and where he teaches till date.

At a time when AI wasnt yet a buzzword, it caught the attention of the man whose great passion has been to make information technology accessible to poorer nations. Thus began a lifelong journey during which hes pushed thinking on the subject into newer dimensions. AI's use in looking for patterns amidst large sets of data, dates back several decades. What makes recent developments in the area, including products like ChatGPT and Bard, so exciting is that they are products of what is commonly referred to as generative AI.

And it is to this that much of Reddy's work over the last 50 years has been dedicated.

While he was on the computer science faculty at Carnegie Mellon in the 1970s, Reddy led a project to construct a computer program that could understand continuous human speech. The difficulties were enormous because of the differences with written text. Thats where Reddy came in with his insight that the issues in speech understanding were central to AI generally.

The result of his early work was Hearsay I, which comprised a set of cooperating parallel processes, each representing a different source of knowledge - acousticphonetic, syntactic, semantic - to predict what may appear in a given context or to verify a hypothesis resulting from a previous prediction. Effectively, Hearsay I was capable of continuous speech recognition. Along with its successors, it created the underlying basis for modern commercial speech recognition technology. An indirect consequence of his work was the famous blackboard model for assimilating and deploying multiple knowledge sources to address a defined problem statement. The model is now adopted across the spectrum of applied artificial intelligence.

In 1994, Reddy received the highest honor in computer science when he was given the A.M. Turing Award (jointly with Edward Feigenbaum) for pioneering the design and construction of large scale artificial intelligence systems, demonstrating the practical importance and potential commercial impact of artificial intelligence technology. Indeed, there isnt a major award that he hasnt won - the French Legion of Honour in 1984, the IBM Research Ralph Gomory Fellow Award in 1991, the Padma Bhushan in 2001, the Okawa Foundation Okawa Prize in 2004, the Honda Foundation Honda Prize in 2005, and the U.S. National Science Board Vannevar Bush Award in 2006.

Unaffected by his success, he still dreams of a world where those at the bottom of the pyramid can benefit from the technologies that he and others are helping to create. In a speech in 2021 when he was conferred the Computer History Museum Fellow Award for his lifes work on artificial intelligence, robotics, and computer science education, Reddy said Looking further in the future I see the emergence of personalized guardian angels that will get the right information to the right people at the right time in the right language with the right level of detail.
