Bayesian Neural Network Treasure Hunt Predictor
This project addresses the complex geospatial modeling challenge presented by Project Skydrop, a real-world treasure hunt requiring the discovery of a hidden prize using clues. By leveraging data clues taken from the hidden location and conditioning global context from satellites, we reason about the relative likelihood of the treasure’s position across a shrinking search grid.…

Distributed Cloud Computing for Machine Learning
The goal of this project is to understand how modern deep learning frameworks scale training across multiple devices. Rather than treating distributed training as a black box, this project focuses on the underlying principles that make large-scale learning possible, such as parallelism, communication, and synchronization. To explore these ideas in practice, I implement a custom…

Neural Network Path-traced Anti-aliasing and Noise Reduction
Rendering realistic images is always a balance between accuracy and speed. If you’ve ever played a video game after seeing a rendered cinematic trailer and left less than impressed, you’ve seen this problem firsthand. This project is about tackling one of the big bottlenecks: getting clean, sharp images from path tracing without paying the huge…
