About Me

I am currently a CS Ph.D student at Duke University, advised by Prof. Cynthia Rudin.

I am broadly interested in Machine Learning, Optimization and Data Mining. My goal is to design simple and interpretable models, which have performance comparable to black-box models, for decision making problems. These techniques can be further applied to interdisciplinary areas with economic, finance and healthcare.

Before joining Duke, I received my B.Sc in Computer Science from the University of British Columbia, with distinction.

Optimal Sparse Regression Trees
Optimal Sparse Regression Trees

We propose a dynamic-programming-with-bounds approach to the construction of provably-optimal sparse regression trees. We leverage a novel lower bound based on an optimal solution to the k-Means clustering algorithm in 1-dimension over the set of labels. We are often able to find optimal sparse trees in seconds.
