Academic Work

I've taken many classes at MIT. I'm particularly proud of my final projects for my classes. Hopefully they pique your interest.

Comparing Machine Learning Methods for Detecting Facial Expressions

We explored both a convolutional neural net approach and PCA multiclass SVM approach for facial expression recognition. Project for graduate machine learning class (6.867 fall 2015).

Bayesian Reinforcement Learning

We explored two approaches to Bayesian reinforcement learning. The first is based on Markov decision processes, and the second is an application of Gaussian processes to Gaussian process temporal difference (GPTD). Project for Bayesian inference and modeling course (6.882 spring 2016).

Undirected Graph Connectivity in Log Space

Survey of Omer Reingold's landmark result proving that undirected graph connectivity can be done in log space, covering the intuition of the key zigzag product. Project for Advanced Complexity Theory (6.841 spring 2016).

Dynamic Graph Streaming Algorithms

Survey of the use of the L0 sketch technique to graph processing algorithms on dynamic graph streams. Project for Advanced Algorithms (6.854 spring 2016).
