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.

preprints

scoring black-box models for adversarial robustness

jian vora, pranay reddy samala

adversarially robust models have sharper explanations and sparser lime weights, use this as a good subsitute for robust accuracy where trying to find attacks to the model can be hard

plug&play multimodal generative model allowing tractable inference

jian vora, isabel valera, guy van den broeck, antonio vergari

learn a joint distribution over multiple modalities while allowing for efficient marginalization, conditioning, likelihood evaluation using probabilisitc circuits on the fused latent space

joint speech-text pre-training with application to text adaptation for asr

jian vora, cekic metehan, dhanush bekal, karel mundnich, srikanth ronanki, katrin kirchoff

a hubert-based shared encoder for speech and text modalities for better coherence in embeddings using a small amount of paired multimodal data, application to text adaptation for asr

other selected research + course projects

efficient learning of log-concave mixtures

jian vora, vivek borkar

random projections of data drawn from a mixture of log-concave densities are provably distributed as a gaussian mixture in the subspace

tractable cooperative multi-agent reinforcement learning

learn a joint policy over actions of all agents allowing for efficient inference by modeling q-function to be a factor graph

improving inference in latent variable models

improved inference in VAEs by reducing two gaps -- approximation gap by using hierarchical VAEs and amortization gap by performing unamortized inference

spatio-temporal action detection and classification

participated in the trecvid'19 challenge which involved performing action detection and classification in videos. proposed a stage-wise architecture of object detection followed by tracking and activity classification
