Top 10 Machine Learning Researchers In India


Research in AI started soon after the Indian government launched the Knowledge-Based Computing Systems (KBCS) program in conjunction with the United Nations Development program in 1991. Later, a number of nodal centres were set up to focus on various research including expert systems in IIT Madras, a speech processing centre in Tata Institute of Fundamental Research, parallel processing in Indian Institute for Science, image processing in Indian Statistical Institute, and natural language processing in Centre for Development of Advanced Computing.

The top 10 names chosen by Analytics India Magazine were based on various parameters such as their PhD degree, patent papers and authored technical publications, pioneering work, knowledge and many more. We mined LinkedIn and H-Index data for the same. Here are top ten artificial intelligence and machine learning researchers presented in an alphabetical order.
