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…
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…
Evolutionary origin of the bipartite architecture of dissipative cellular networks
Bowen Shi, Long Qian, Qi Ouyang
Recently, plenty research has been done on discovering the role of energy dissipation in biological networks, most of which focus on the relationship of dissipation and functionali…
Geometry of optimal control in chemical reaction networks
Yikuan Zhang, Qi Ouyang, Yuhai Tu
Although optimal control (OC) has been studied in stochastic thermodynamics for systems with continuous state variables, less is known in systems with discrete state variables, suc…
Temperature Compensation through Kinetic Regulation in Biochemical Oscillators
Haochen Fu, Chenyi Fei, Qi Ouyang +1
Nearly all circadian clocks maintain a period that is insensitive to temperature changes, a phenomenon known as temperature compensation (TC). Yet, it is unclear whether there is a…
Free energy dissipation enhances spatial accuracy and robustness of Turing pattern in small reaction-diffusion systems
Dongliang Zhang, Chenghao Zhang, Qi Ouyang +1
Accurate and robust spatial orders are ubiquitous in living systems. In 1952, Alan Turing proposed an elegant mechanism for pattern formation based on spontaneous breaking of the s…
