LAVa: Layer-wise KV Cache Eviction with Dynamic Budget Allocation

EMNLP 2025

KV Cache is commonly used to accelerate LLM inference with long contexts, yet its high memory demand drives the need for cache compression. Existing compression methods, however, are largely heuristic and lack dynamic budget allocation. To address this limitation, we introduce a unified framework fo

daDPO: Distribution-Aware DPO for Distilling Conversational Abilities

ACL 2025finding

Large language models (LLMs) have demonstrated exceptional performance across various applications, but their conversational abilities decline sharply as model size decreases, presenting a barrier to their deployment in resource-constrained environments. Knowledge distillation (KD) with Direct Prefe…

Reward Difference Optimization For Sample Reweighting In Offline RLHF

EMNLP 2024finding

With the wide deployment of Large Language Models (LLMs), aligning LLMs with human values becomes increasingly important. Although Reinforcement Learning with Human Feedback (RLHF) proves effective, it is complicated and highly resource-intensive. As such, offline RLHF has been introduced as an alte…
