Tianqi Tang, Shohreh Deldari, Hao Xue, Celso De Melo, Flora D. Salim·June 19, 2024

Summary

ViLCo-Bench is a groundbreaking benchmark for video-language continual learning, addressing the lack of standardized platforms in multimodal research. It evaluates models on adapting to new tasks with video and text inputs while preserving prior knowledge, focusing on non-classification tasks like episodic memory, cross-modal understanding, and multi-task learning. The benchmark, derived from the Ego4D dataset, presents three challenges: video-language understanding, multi-label annotation, and query-incremental learning. It features curated tasks for moment, natural language, and visual queries, with varying complexities and annotation formats. The study proposes a memory-efficient framework incorporating self-supervised learning, comparing state-of-the-art methods and demonstrating the effectiveness of a proposed method, VilCo, which outperforms others in long-term video analysis and multimodal interactions. Future work aims to expand tasks, address annotation limitations, and explore egocentric applications.
