Dr. Avisek Gupta

Post Doctoral Fellow, IAI – TCG CREST




Research

I am currently working in the areas of unsupervised data clustering and weakly supervised learning. In the area of data clustering, I have previously focused on factors affecting the performance of center-based clustering methods – the features used, the distance metric that can be learnt, the number of clusters that can be identified, etc. Recently I have been interested in the general area of weakly supervised learning, and how low-effort supervision from experts can be provided to guide the learning process of a statistical model.



Education


I completed my Ph.D. degree in Computer Science at the Indian Statistical Institute, Kolkata, in November 2021. I received my B.Tech. and M.E. degrees in Computer Science & Engineering from the West Bengal University of Technology (currently the Maulana Abul Kalam Azad University of Technology, West Bengal) in 2012 and Jadavpur University in 2014, respectively. I worked on a SERB project on Bengali document querying, clustering and summarization from July 2014 to May 2015 at Jadavpur University. Prior to joining TCG Crest, I worked as a Visiting Scientist at the Electronics and Communication Sciences Unit, Indian Statistical Institute Kolkata, from December 2021 to March 2022.



Courses

I was an organizing chair for the recent Winter School on Deep Learning 2022, organized by ECSU at the Indian Statistical Institute, Kolkata.

I have been a Teaching Assistant for the following courses:

  • Computer Vision (Second Year M.Tech. CS, ISI Kolkata) 2019-20, with Dr. Swagatam Das.
  • Computing for Data Sciences (First Year PGDBA, ISI Kolkata) 2018-2019, with Dr. Swagatam Das. The course website can be viewed from this [Link].
