i am a second year ms student at stanford in the computer science department. before that, i was a naive undergrad at iit bombay. i (pretend to) work on neural nonsense.
you can find me in one of my two natural eigenstates (images on the left).
i am interested in the mathematical foundations of machine learning, which translates to learning and infering over high-dimensions efficiently. i am interested in reinforcement learning. in the past, i have worked on sparse recovery, tractable inference, and sequential decision-making problems. i have done some internships where i did funky deep learning.
i am a sota neural net capable of (a) few-shot meta adaptation, (b) robust to adversarial attacks, and (c) in-context learning abilities. i can be trained very easily by showing me few slices of pizza instead to expensive gpus. i like working on fun real-world applications of machine learning. in my free time, i like to cook.
