Selected Research

Building a 100x Cheaper Trace Judge with Fireworks

LangChain x Fireworks, June 2026 - Fine-tune a small open model to judge production agent traces at frontier-level accuracy for a fraction of the cost.

CNN2Graph: Building Graphs for Image Classification

WACV 2023 - Use GNNs to build a graph of “good” images and use these good images to better classify query images via transductive learning.

Image Retrieval with Self-Supervised Divergence Minimization and Cross-Attention Classification

IJCAI 2024 -Improve image retrieval by letting augmenting query images and making their distributions match across the database.

Learning Object Focused Attention

ICPR 2024 - Work on developing attention mechanisms that focus on relevant objects within images for better understanding and classification.
