Dynamic Collaboration of Multi-Language Models based on Minimal Complete Semantic Units

EMNLP 2025

This paper investigates the enhancement of reasoning capabilities in language models through token-level multi-model collaboration. Our approach selects the optimal tokens from the next token distributions provided by multiple models to perform autoregressive reasoning. Contrary to the assumption th

HoPE: Hybrid of Position Embedding for Long Context Vision-Language Models

NeurIPS 2025poster

Vision-Language Models (VLMs) have made significant progress in multimodal tasks. However, their performance often deteriorates in long-context scenarios, particularly long videos. While Rotary Position Embedding (RoPE) has been widely adopted for length generalization in Large Language Models (LLMs…

Learning Harmonized Representations for Speculative Sampling

ICLR 2025poster

Speculative sampling is a promising approach to accelerate the decoding stage for Large Language Models (LLMs). Recent advancements that leverage target LLM's contextual information, such as hidden states and KV cache, have shown significant practical improvements. However, these approaches suffer f…
