Noise-Driven Exploration and Transient Freezing Select Flat Minima in Stochastic Gradient Descent
Ning Yang, Yikuan Zhang, Qi Ouyang +2
Stochastic gradient descent (SGD) is central to deep learning, yet the dynamical origin of its preference for flatter, more generalizable solutions remains unclear. Here, by analyz…

Optimal Discretization in Hour-Glass Molecular Clocks Driven by Oscillating Free Energy
Zhuangcheng Zhen, Kaiyue Shi, Qi Ouyang +1
Hour-glass clocks do not free-run; they keep time by riding an external rhythm. Motivated by the primordial KaiBC system in cyanobacteria, we study a driven, finite-state molecular…

An altruistic resource-sharing mechanism for synchronization: The energy-speed-accuracy tradeoff
Dongliang Zhang, Yuansheng Cao, Qi Ouyang +1
Synchronization among a group of active agents is ubiquitous in nature. Although synchronization based on direct interactions between agents described by the Kuramoto model is well…
