I am an undergraduate student at BITS Pilani, Goa Campus where I'm pursuing Bachelor of Engineering in Computer Science. I am currently working with Prof. Ashwin Srinivasan , Prof. Sidong Liu and Prof. Tanmay Verlekar at APPCAIR on developing a generalist AI for grounded radiology reports.

I have also recently started contributing to DeepChem, currently focusing on the Materials Science part of the librtary. Thanks to my small RA at the Graph and Geometric Learning Lab at Yale, I have read several papers on GNNs focusing on vario(oo)us aspects.

I am also the General Secretary of SAiDL, Society for Artificial Intelligence and Deep Learning at BITS Goa; we try to inculcate a spirit of AI and DL in the university through open source projects and personalised courses. My research interests, clearly, revolve around Graph Neural Networks, Multimodal Multitask Learning, Machine Perception and (some) Reinforcement Learning.

In my free time you'll probably find me reading up on theoretical computer science (sorry, not sorry). I am a pretty radical supporter of R&B and rap. Apart from this, I love to teach (just about anything). I (would) also like (to) play Table Tennis, though I have not played competitively since 2019.

Research Assistant | Graph and Geometric Learning Lab, Yale
October '23 - January '24

Presented papers to the lab and read up on a large aspects of GNNs, starting from core GNN architecture research to efficient sampling methods for few and one shot learning techniques. Also ran baselines like TransE, QuatE, etc. on KG level tasks. You can see the presentations/papers here! (Indexed according to the appropriate week/presentation number)

Undergraduate Researcher | APPCAIR & Macquarie University (Australia)
August '23 - Present

Building a generalist (multi-modal) AI for Chest X-rays (using the Stanford CheXpert dataset), which can tutor, generate and correct radiology reports; as well as retrieve images according to a radiology report. Our main focus is on Coherent Report Generation.

Jan '24 - Present

Also working on Spatio-Temporal GNNs for detecting Ataxia patients; Our main focus here si to utilise the underlying graph structure of the human body to detect anomalies in the movement of the body.

ML Intern | VoiceQube
June '23 - August '23

Worked on an AI research project to incorporate explicit sentiment analysis into effective stock market trading solutions.


Open-Source Molecular Processing Pipeline for Generating Molecules
S. Vinaya, J. Siguenza, K. Bania*, B. Ramsundar

Under review at the GEM Workshop, a part of ICLR 2024.


Image Segmentation on arbitrary prompts using Open AI's CLIP
Respository

I tried out various loss functions for segmentation (on PhraseCut dataset) and various model depths. Increased the inference time processing speed by training a light-weight decoder. Basically reproduced the CLIPSeg Paper. My results show that the model's performance can be improved vastly by using a better loss function. (~28% improvement in mIOU using DiceLoss vs using BCELoss for same number of iterations)

Reinforcement Learning as a Sequence Modelling Task
Respository

Read up on decision transformers and replaced them with other sequence models; LSTMs, GRUs and an Elman RNN and compared them to each other, with the primary goal of long-term credit assignment robustness (did also check for extrapolation) on the Hopper environment. (The figure is a display of the results on LSTMs - Medium (offline data) - Normal (Rewards), Left = Returns, Right = Episode Length)


Rank-N-Contrast

Amazing paper + I read the proofs too 🫡

Punch, Kick, Duck!

This took me a while but I am ranked 9th in the world in this game's first level! xD

As of 11/01/24

My repository on cs224w's (Stanford Machine Learning with Graphs) assignment solutions is the only one with solutions to all problems (not just coding assignments)!

Craziest paper on GNNs so far!
