Revisiting Multimodal KV Cache Compression: A Frequency-Domain-Guided Outlier-KV-Aware Approach

arXiv — cs.LGMonday, November 24, 2025 at 5:00:00 AM
  • A new approach to multimodal KV Cache compression has been proposed, focusing on the distribution of KV matrices' energy in the frequency domain. This method identifies and removes outlier KV pairs that deviate from the principal energy, which significantly impacts the performance of multimodal large language models (MLLMs). The study highlights the limitations of existing compression methods that rely solely on attention scores.
  • This development is crucial as it addresses the substantial inference overhead faced by multimodal models, which grow in cache size with increased visual input. By improving cache compression, the proposed method enhances the efficiency of MLLMs, potentially leading to faster processing times and reduced computational costs in applications that utilize these models.
  • The advancement in KV Cache compression aligns with ongoing efforts to enhance the capabilities of MLLMs, particularly in spatial reasoning and temporal understanding. As researchers explore various strategies to optimize multimodal processing, the focus on frequency-domain analysis and outlier management reflects a broader trend towards more efficient and effective AI models that can handle complex audio-visual scenarios.
