Deja Vu: Efficient Video-Language Query Engine with Learning-based Inter-Frame Computation Reuse

Summary: Deja Vu accelerates ViT-based VideoLM query processing by learning inter-frame computation reuse via ReuseViT. Memory–compute joint compaction converts reduced FLOPs into GPU speedups, achieving up to 2.64× faster embeddings within 2% error. (summarized by gpt-5.6-luna on Jul 24 2026)
