CoViPAL: Layer-wise Contextualized Visual Token Pruning for Large Vision-Language Models

EMNLP 2025

Large Vision-Language Models (LVLMs) process multimodal inputs consisting of text tokens and vision tokens extracted from images or videos. Due to the rich visual information, a single image can generate thousands of vision tokens, leading to high computational costs during the prefilling stage and

ToM: Leveraging Tree-oriented MapReduce for Long-Context Reasoning in Large Language Models

EMNLP 2025

Large Language Models (LLMs), constrained by limited context windows, often face significant performance degradation when reasoning over long contexts. To address this, Retrieval-Augmented Generation (RAG) retrieves and reasons over chunks but frequently sacrifices logical coherence due to its relia
