Syamantak Kumar
I am a second year PhD student studying computer science at UT Austin advised by Prof. Purnamrita Sarkar and Prof. Kevin Tian . Broadly, my research interests lie at the intersection of statistics and machine learning.
I am interested in designing machine learning algorithms with provable guarantees of convergence and correctness. I also want to work on quantifying the computational and statistical aspects of state-of-the-art deep learning methods.
I deeply enjoy studying the applications of high-dimensional statistics, optimization and probability theory to real-world problems.
Previously, I was an undergraduate student at the Computer Science and Engineering Department, IIT Bombay .
I previously worked with Prof. Suyash Awate on Medical Imaging and with Prof. Preethi Jyothi on NLP for Code-switching at IIT Bombay.
I have also worked with Prof. Thomas Deserno on Medical Informatics and Imaging, back in 2018.

Generative Model for User Contributions
I worked at Google, Bangalore with the Maps team on a model for predicting the correctness of an edit made by a user on Maps. This model is used to ensure that data displayed on Google Maps is true to the accuracy it claims.
