CoMeT: Collaborative Memory Transformer for Efficient Long Context Modeling

Runsong Zhao, Shilei Liu, Jiwei Tang +8

The quadratic complexity and indefinitely growing key-value (KV) cache of standard Transformers pose a major barrier to long-context processing. To overcome this, we introduce the…

PoC: Performance-oriented Context Compression for Large Language Models via Performance Prediction

Runsong Zhao, Shilei Liu, Jiwei Tang +8

While context compression can mitigate the growing inference costs of Large Language Models (LLMs) by shortening contexts, existing methods that specify a target compression ratio…

Expert Divergence Learning for MoE-based Language Models

Jiaang Li, Haibin Chen, Langming Liu +9

The Mixture-of-Experts (MoE) architecture is a powerful technique for scaling language models, yet it often suffers from expert homogenization, where experts learn redundant functi…

PretrainRL: Alleviating Factuality Hallucination of Large Language Models at the Beginning

Langming Liu, Kangtao Lv, Haibin Chen +8

Large language models (LLMs), despite their powerful capabilities, suffer from factual hallucinations where they generate verifiable falsehoods. We identify a root of this issue: t…
