Meta Reinforcement Learning - Reward Decompostion
I’m working with Jack Lindsey as part of the Litwin-Kumar Lab at the Zuckerman Institute on developing meta-RL algorithms that learn more efficient learning rules. I’m further interested in RL algorithms that decompose the reward signal to accelerate learning.
Generalized Multi-Agent Framework To Simulate Deviant Mining Strategies on Bitcoin-like Blockchains
We first present a taxonomy of existing deviant mining strategies and parametrise them using a common set of variables. We then design a simulator that is capable of testing proof-of-work blockchain systems for this repertoire in a multi-agent setting, and provide insight. Check out our poster here, a paper draft is in the works! Work done with the Math Department at Columbia University
Interactive Metric Learning under sparse signaling
This is an incomplete project (currently paused). I’m working on developing a metric learning algorithm that performs perceptron-like online updates using split-merge signals on data clusters. Advised by Prof. Nakul Verma
Memorial Sloan Kettering Cancer Centre - CBSP Program
I got paired with MSKCC’s m-ski Lab as a part of the CBSP summer program. Unfortunately this experience was cut short due to Covid. I replicated analyses with dryclean - a statistical tool to denoise genomic coverage data.
Predicting gene expression using Transfer Learning and Attention
With Shiu Lab at Michigan State University, I built an interpretable deep learning model equipped with the attention mechanism that predicted whether genes in certain crops were expressed in response to environmental stress. Futhermore we transfer learnt TF binding motifs from A. thaliana to O. sativa and showed how certain binding sites were preserved across species. See the poster that I presented at the MidSure research symposium
2017: SSP Biochemistry - Designing a fungal enzyme inhibitor
I worked on a mentored research project with a team, as part of SSP Biochemistry at Purdue University, to design a fungal enzyme inhibitor using wet lab techniques as well as computational modelling and simulation software.
