Faster Adaptive Optimization via Expected Gradient Outer Product Reparameterization
Published in SIAM Journal on Mathematics of Data Science (under review), 2025
Tightens Adagrad/Adam convergence bounds by a factor of 1/d via EGOP-based reparameterization, and proposes Auxiliary-Variable and Reduced EGOP algorithms that bypass the storage/compute bottleneck of full-matrix preconditioning. Submitted to SIMODS.

Validating Two Pathological Foundation Models for Breast Biomarker Detection
Published in In preparation, 2025
First study transferring Direct Preference Optimization (DPO) from LLM alignment to computational pathology. A label-free preference-pair pipeline (UMAP + DBSCAN on TITAN embeddings) plus LoRA-DPO fine-tuning lifts PR-status AUROC from 79.75% to 81.92% and Cohen’s κ from 45.40% to 54.43%. In preparation.
