Artificial Intelligence and Machine Learning (AI-ML) are intertwined with every aspect of our daily lives. Their pertinence is increasing with time as well. The AI-ML group at TCG CREST is motivated to achieve excellence in this field through fundamental, human-centric and sustainable research. The primary goal is to deliver path-breaking research outputs and fantastic PhD theses. The researchers in this group are already carrying out collaborative research with premier institutes in India and abroad. The group strives to expand its research network globally in the long run.  The group mostly works in the following areas of specialization.

  • Statistical Learning Theory
  • Deep Neural Networks
  • Representation Learning
  • Deep Generative Models
  • Computer Vision
  • Natural Language Processing
  • Large Language Models
  • Climate Informatics
  • AI in Law
  • Privacy-preserving Learning






  • Developed a search engine on Legal summarization.

  • Maintained a Covid Bulletin in Indian context for last two years (ongoing). [Covid-19 R_0 Estimation]
  • We have an industry sponsored project on “Development of sentiment and emotion analysis algorithms from market news, blogs, social network data and evaluation of these algorithms by computing cross correlation between outputs of these algorithms with typical stock market index such as nifty fifty”
