Researchers have developed SPARE, a novel method for pruning visual tokens in Vision Language Models (VLMs) to improve efficiency. Unlike previous diversity-focused approaches, SPARE reformulates token reduction as a subspace reconstruction problem, minimizing reconstruction error by selecting tokens with large projection residuals. The method also incorporates an "anti-relevance" criterion, prioritizing tokens with lower image-text relevance to better preserve contextual information. Applied to LLaVA, SPARE can remove up to 94% of visual tokens with minimal performance loss, operating in a training-free manner. AI
IMPACT This method could significantly reduce computational costs for VLMs, enabling wider deployment and faster inference.
