  • Enhancing Exploratory Capability in Visual Navigation using Uncertainty of Implicit Scene Representations [arXiv] [code]
    Yichen Wang, Qiming Liu, Zhe Liu, Hesheng Wang
    37th IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2024 (Oral)
  • The φ Curve: The Shape of Generalization through the Lens of Norm-based Capacity Control [arXiv] [code]
    Yichen Wang, Yudong Chen, Lorenzo Rosasco, Fanghui Liu
    [TLDR: We precisely characterize how the generalization learning curve behaves under a suitable model capacity and rigorously prove (Fig. 8.12, CS229 Lecture Notes).]
    39th Conference on Neural Information Processing Systems (NeurIPS), 2025
  • From Spectra to Joint Schedules in LLM Pre-training: 3+3(+2) Scaling-Law Regimes [arXiv] [code]
    Yichen Wang, Fanghui Liu, Yudong Chen
    [TLDR: We characterize when spectral structure produces power-law learning curves and how learning-rate and batch-size schedules change them, with empirical validation in LLM pre-training.]
    arXiv preprint, 2026
