Beyond Bellman: High-Order Generator Regression for Continuous-Time Policy Evaluation
Yaowei Zheng, Richong Zhang, Shenxi Wu +5
We study finite-horizon continuous-time policy evaluation from discrete closed-loop trajectories under time-inhomogeneous dynamics. The target value surface solves a backward parab…
Hyperparameter Transfer Laws for Non-Recurrent Multi-Path Neural Networks
Shenxi Wu, Haosong Zhang, Xingjian Ma +4
Deeper modern architectures are costly to train, making hyperparameter transfer preferable to expensive repeated tuning. Maximal Update Parametrization (P) helps explain why ma…
Quantifying energy landscape of high-dimensional oscillatory systems by diffusion decomposition
Shirui Bian, Ruisong Zhou, Wei Lin +1
High-dimensional networks producing oscillatory dynamics are ubiquitous in biological systems. Unravelling the mechanism of oscillatory dynamics in biological networks with stochas…
Utilizing Causal Network Markers to Identify Tipping Points ahead of Critical Transition
Shirui Bian, Zezhou Wang, Siyang Leng +2
Early-warning signals of delicate design are always used to predict critical transitions in complex systems, which makes it possible to render the systems far away from the catastr…
