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…
A Qualitative Test-Risk Mechanism for Scaling Behavior in Normalized Residual Networks
Daning Cheng, Zeyu Liu, Jun Sun +4
The scaling behavior, in which test performance often improves as model size and data increase, is a central empirical phenomenon in modern deep learning, yet its theoretical basis…
Co-GRPO: Co-Optimized Group Relative Policy Optimization for Masked Diffusion Model
Renping Zhou, Zanlin Ni, Tianyi Chen +6
Recently, Masked Diffusion Models (MDMs) have shown promising potential across vision, language, and cross-modal generation. However, a notable discrepancy exists between their tra…
