A Book Recommendation System

post, app

I built a book recommendation system in which you can input books you like and dislike, and the app recommends some books for you. Check it out!

A Generalized Elo System for Tennis Players

repo, post 1, post 2, post 3 (graphics)

I built a generalized Elo rating system for tennis players which improves upon the model presented by FiveThirtyEight. The improvements are as follows.

1. I eliminate the need to set hyperparameters by hand. This makes my model more generalizable to other settings and less time-consuming to fine-tune.
2. I decreased log-loss error by 1.5% from FiveThirtyEight’s model for 2015-2019 test data.

Robustness of Neural ODEs

This was a deep learning research project. I conducted statistical tests to determine if decreasing step size in Neural ODE approximations results in increasing robustness against adversarial attacks. I concluded that step size has a significant, but not gigantic, statistical effect on robustness of Neural ODE approximations in certain settings.

You can read my introduction to Neural ODEs here and a little bit about their adversarial robustness here.

Fluctuations of an Exclusion Process

This was a pure math research project. I established quantitative bounds on the distribution of a statistic of an interacting particle system similar to the totally asymmetric simple exclusion process. My visual introduction to exclusion processes can be found here.
