Mark Rhee

I'm a (applied) mathematics student at UC Berkeley with intended minors in computer science and physics. My interests lie at the intersection of fields such as math, computer science, physics, and philosophy. I'm particularly interested in the mathematical foundations of machine learning.

At Berkeley, I've taken a wide range of classes—mostly whatever I found interesting. You can find a list of all the (cool) classes I've taken so far and my thoughts on them here. I store notes and random musings here. Check it out if you want a peek into my brain.

Expository Works

Occam's Razor and Honesty with respect to Beliefs
October 2025

Contrasting MacKay's classic Bayesian Occam's Razor with the modern perspective of Wilson et al: a justification for complex, overparameterized models.

Projects

Comparing Learning Dynamics of Gradient Descent and Muon optimizer
August 2025
Github Repo

Under construction.

Generalization Capabilities of Neural Network Substructure Ensembles
August 2025
Github Repo

Showed that ensembles of sparse subnetworks can vastly outperform dense networks while improving out-of-distribution generalization. This work highlights how sparsity and functional redundancy can be leveraged for more robust learning.

NBA Shot Prediction
December 2024
Github Repo

Predictive modeling of NBA shot success using features like shot distance and defender proximity. Trained logistic regression and neural networks. Features analysis by training models with individual variables.
