LLMs as Noisy Channels: A Shannon Perspective on Model Capacity and Scaling Laws

ICML 2026poster

Existing scaling laws for Large Language Models (LLMs), predominantly monotonic power laws, have successfully guided model development but fail to explain emerging non-monotonic phenomena such as catastrophic overtraining and quantization-induced degradation, where performance deteriorates despite i…

SPARKLING: Balancing Signal Preservation and Symmetry Breaking for Width-Progressive Learning

ICML 2026poster

Progressive Learning (PL) reduces pre-training computational overhead by gradually increasing model scale. While prior work has extensively explored depth expansion, width expansion remains significantly understudied, with the few existing methods limited to the early stages of training. However, ex…

FlexPrefill: A Context-Aware Sparse Attention Mechanism for Efficient Long-Sequence Inference

ICLR 2025oral

Large language models (LLMs) encounter computational challenges during long-sequence inference, especially in the attention pre-filling phase, where the complexity grows quadratically with the prompt length. Previous efforts to mitigate these challenges have relied on fixed sparse attention patterns…

Model Merging in Pre-training of Large Language Models

NeurIPS 2025poster

Model merging has emerged as a promising technique for enhancing large language models, though its application in large-scale pre-training remains relatively unexplored. In this paper, we present a comprehensive investigation of model merging techniques during the pre-training process. Through exten…

Acu-Net: A 3D Attention Context U-Net for Multiple Sclerosis Lesion Segmentation

ICASSP 2020accepted

Multiple Sclerosis (MS) lesion segmentation from MR images is important for neuroimaging analysis. MS is diffuse, multifocal, and tend to involve peripheral brain structures such as the white matter, corpus callosum, and brainstem. Recently, U-Net has made great achievements in medical image segment…
