HybridThinker: Efficient Chain-of-Thought Reasoning via Compressed Memory and Transient Thought Steps

Xin Liu, Runsong Zhao, Xinyu Liu +8

Extended chain-of-thought (CoT) traces improve LLM reasoning but incur substantial computational and memory costs. While existing CoT compression methods mitigate this by condensin…

MemoSight: Unifying Context Compression and Multi Token Prediction for Reasoning Acceleration

Xinyu Liu, Xin Liu, Bo Jin +8

While chain-of-thought (CoT) reasoning enables LLMs to solve challenging reasoning tasks, the linear growth of the KV cache leads to substantial memory and inference overhead. Exis…

OISD: On-Policy Internal Self-Distillation of Language Models

Xinyu Liu, Darryl Cherian Jacob, Yang Zhou +2

Recent reinforcement learning (RL) post-training approaches primarily optimize the final output policy using sparse outcome-level rewards, while largely overlooking predictive sign…

Autoencoding-Free Context Compression for LLMs via Contextual Semantic Anchors

Xin Liu, Runsong Zhao, Pengcheng Huang +7

Context compression is an advanced technique that accelerates large language model (LLM) inference by converting long inputs into compact representations. Existing methods primaril…

Position IDs Matter: An Enhanced Position Layout for Efficient Context Compression in Large Language Models

Runsong Zhao, Xin Liu, Xinyu Liu +4

Using special tokens (e.g., gist, memory, or compressed tokens) to compress context information is a common practice for large language models (LLMs). However, existing approaches…

Forgetting Curve: A Reliable Method for Evaluating Memorization Capability for Long-context Models

Xinyu Liu, Runsong Zhao, Pengcheng Huang +5

Numerous recent works target to extend effective context length for language models and various methods, tasks and benchmarks exist to measure model's effective memorization length…
