Autoregressive Denoising Score Matching is a Good Video Anomaly Detector

ICCV 2025poster

Video anomaly detection (VAD) is an important computer vision problem. Thanks to the mode coverage capabilities of generative models, the likelihood-based paradigm is catching growing interest, as it can model normal distribution and detect out-of-distribution anomalies. However, these likelihood-ba…

Building a Multi-modal Spatiotemporal Expert for Zero-shot Action Recognition with CLIP

AAAI 2025technical

Zero-shot action recognition (ZSAR) requires collaborative multi-modal spatiotemporal understanding. However, finetuning CLIP directly for ZSAR yields suboptimal performance, given its inherent constraints in capturing essential temporal dynamics from both vision and text perspectives, especially wh…
