Quantifying Depth Sufficiency in Residual Neural Networks: A First-Order Criterion

Zeyu Liu, Jinhao Zhang, Yunquan Zhang +4

How can we determine whether a trained neural network is already deep enough? We study this under a fixed function-preserving residual-growth protocol specifying insertion location…

Mechanisms of Width Scaling in Normalized Residual Networks: The Effective Alignment Dimension

Jinhao Zhang, Zeyu Liu, Zicheng Yan +4

Existing theories of neural-network width characterize asymptotic limits, but provide limited guidance on whether an expansion direction identified from finite training data remain…

HeRo-Q: A General Framework for Stable Low Bit Quantization via Hessian Conditioning

Jinhao Zhang, Yunquan Zhang, Zicheng yan +3

Post Training Quantization (PTQ), a mainstream model compression technique, often leads to the paradoxical 'low error, high loss' phenomenon because it focuses solely on minimizing…

Attention Dispersion in Dynamic Graph Transformers: Diagnosis and a Transferable Fix

Jinhao Zhang, Kangfei Zhao, Qiuhao Zeng +1

Transformer-based architectures have become the dominant paradigm for Continuous-Time Dynamic Graph (CTDG) learning, yet their performance remains limited on temporally shifted dat…

CALM: A CKA-Guided Adaptive Layer-Wise Modularization Framework for LLM Quantization

Jinhao Zhang, Yunquan Zhang, Daning Chen +2

Current mainstream post-training quantization methods for large language models typically apply a uniform quantization strategy across all network layers, overlooking the substanti…

MoQE: Improve Quantization Model performance via Mixture of Quantization Experts

Jinhao Zhang, Yunquan Zhang, Boyang Zhang +2

Quantization method plays a crucial role in improving model efficiency and reducing deployment costs, enabling the widespread application of deep learning models on resource-constr…
