Hello! I am Arkaprava Sinha, a Graduate Research Assistant pursuing a Ph.D. in Computer Science at the University of North Carolina, Charlotte. I am advised by Prof. Srijan Das. My research focuses on Video Understanding, Multimodal Learning, and Temporal Action Detection. I have prior experience as a Data Scientist, contributing to innovative projects in Computer Vision, and Machine Learning.

Research

My research is centered on video representation learning, with a focus on utilizing spatio-temporal attention mechanisms and multiple modalities. I am also deeply interested in Vision-Language Models and Self-Supervised Learning techniques. The primary applications of my research encompass Action Classification in Trimmed Videos, Temporal Action Detection in Untrimmed Videos, Robotic Vision, and the development of Video Conversational Agents.
