Ashim Gupta

I am a PhD student at the School of Computing, University of Utah advised by Prof. Vivek Srikumar. The main area of my research in NLP is the analysis, interpretability, and robustness of NLP models. I also frequently work on low-resource languages like Sanskrit focusing on incorporating Sanskrit specific lingusitc rules into structured prediction models for Sanskrit.

Before this, I was a Research Assistant in the Computer Science Department at IIT Kharagpur. My research advisors at IIT Kharagpur were Prof. Pawan Goyal and Prof. Sudeshna Sarkar. My work at IIT Kharagpur mainly focussed on information extraction from biomedical literature and unsupervised machine translation systems for indic languages.

I completed my Bachelor’s Degree in Electrical Engineering from IIT-BHU in 2016. My undergraduate research advisors were Prof. Rajeev Srivastava and Prof. D. N. Vishwakarma. During my undergraduate, my research involved working on image retrieval systems both in general and medical domain. For my undergraduate thesis, I studied and implemented robust multi-sensor data fusion methods using Kalman Filter.

Some useful lecture notes.

Maximum Likelihood Estimate for Multivariate Gaussian
It is known that for a multivariate Gaussian, maximum likelihood estimate for mean is unbiased and for variance, the estimate is biased. This document has the proof. [pdf]
