Rethinking Local Learning: A Cheaper and Faster Recipe for LLM Post-Training

Hengyu Shi, Tianyang Han, Peizhe Wang +3

LLM post-training typically propagates task gradients through the full depth of the model. Although this end-to-end structure is simple and general, it couples task adaptation to f…

Chain-based Distillation for Effective Initialization of Variable-Sized Small Language Models

Boyu Shi, YiCheng Jiang, Chang Liu +3

Large language models (LLMs) achieve strong performance but remain costly to deploy in resource-constrained settings. Training small language models (SLMs) from scratch is computat…

Hierarchical Dual-Subspace Decoupling for Continual Learning in Vision-Language Models

Mengxin Qin, Xiang Zhang, Kun Wei +2

Class-incremental learning aims to continuously acquire new knowledge while preserving previously learned information, thereby mitigating catastrophic forgetting. Existing methods…

DIMoE-Adapters: Dynamic Expert Evolution for Continual Learning in Vision-Language Models

Mengxin Qin, Xiang Zhang, Xi Wang +3

Continual learning enables vision-language models to accumulate knowledge and adapt to evolving tasks without retraining from scratch. However, in multi-domain task-incremental lea…

Understanding Performance Collapse in Layer-Pruned Large Language Models via Decision Representation Transitions

Boyu Shi, Chang Liu, ChuanBao Gao +2

Layer pruning efficiently reduces Large Language Model (LLM) computational costs but often triggers sudden performance collapse. Existing representation-based analyses struggle to…

Self-Indexing KVCache: Predicting Sparse Attention from Compressed Keys

Xu Yang, Jiapeng Zhang, Dongyang Zhao +2

The KV cache in self-attention has emerged as a major bottleneck in long-context and large-batch inference for LLMs. Existing approaches often treat sparsity prediction and compres…
