AdaCM^2: On Understanding Extremely Long-Term Video with Adaptive Cross-Modality Memory Reduction

CVPR 2025highlight

The advancements in large language models (LLMs) have propelled the improvement of video understanding tasks by incorporating LLMs with visual models. However, most existing LLM-based models (e.g., VideoLLaMA, VideoChat) are constrained to processing short-duration videos. Recent attempts to underst…

HALOC: Hardware-Aware Automatic Low-Rank Compression for Compact Neural Networks

AAAI 2023technical

Low-rank compression is an important model compression strategy for obtaining compact neural network models. In general, because the rank values directly determine the model complexity and model accuracy, proper selection of layer-wise rank is very critical and desired. To date, though many low-rank…
