Projects Database Assistant Agent A LangChain ReAct database agent that enables users to chat with a database using multi-hop reasoning and in-context learning to refine knowledge. It then produces the trail of SQL commands it used to extract knowledge. Robustness Analysis of Neural Networks Exploring techniques to analyze and robustify feature specific dissections of neural networks Single-Shot Localized Retrieval using YOLOv3 A retrieval system that takes object selections as bounding box prompts from the user, given an image and retrievs similar objects from an image database. Publications Computer Vision Explainability in Safety Surveillance An explainability framework for safety surveillance, extending Eigen-CAM to YOLOv5 object detection with relevance-based layer selection for bias diagnosis. Classification on Imbalanced Browse Node data using Transformers Customized DeBERTa with Focal Loss for large-scale e-commerce browse node classification, improving convergence, confidence, and performance on imbalanced product data. Augmented Reality–Enhanced Textbooks Scalable augmented reality pipeline embedding AR markers in textbooks, delivering interactive 3D learning via affordable smartphones for low-income schools; TNSCST-funded.
