CourseTimeQA: A Lecture-Video Benchmark and a Latency-Constrained Cross-Modal Fusion Method for Timestamped QA

The article introduces a new benchmark and a method for question answering on lecture videos. The focus is on timestamped QA, which is a specific and challenging task. The cross-modal fusion method likely aims to combine information from video and audio with text. The latency constraint suggests a focus on real-time or near real-time performance.
