Socially Assistive Robots

A novel fall detection system that enhances the YOLOv7 deep learning architecture to distinguish between fall and non-fall postures in elderly individuals. The system integrates object detection and pose classification in a single inference step, deployed on a NAO humanoid robot for real-time monitoring with immediate caregiver alerts.

An advanced question answering system that enhances relation linking by integrating context-aware semantic knowledge graphs. The system combines lexical information, embedding-based similarity, and entity-level data to improve accuracy and interpretability in retrieving relevant property candidates from knowledge bases.
