01 / Selected project
ckptplan
Cost-aware activation checkpoint planning for PyTorch. Profile a model’s blocks, set a GPU memory budget, and choose what to recompute during training.
Built around GPU memory profiling and dynamic programming, with a Python API, a C++ planning core, and a local benchmark explorer.
02 / Research
Language meets 3D space.
vgrep3d: Open-Vocabulary 3D Object Querying in Gaussian Splatting Scenes via SAM-Guided SigLIP 2 Feature Fields
Ryan Abraham · Undergraduate thesis
York University · Supervised by Prof. James Elder
Exploring text-based object queries inside 3D Gaussian scenes, and the limits of semantic feature fields on real-world driving data.
03 / In motion
vgrep
Search your images with words. A local semantic search tool that matches natural language to image content, without relying on filenames or tags. (Better than Apple photos)
