Revealing more on complex energy landscapes by passing less local information: Cavity approach with trust region in non-convex optimization problems
Zhiqi Xu, Chi Ho Yeung
Energy landscapes of non-convex optimization problems are high-dimensional surfaces that are difficult to reveal, visualize, or analyze. Message-passing algorithms, or equivalently…
Re-routing game: The inadequacy of mean-field approach in modeling the herd behavior in path switching
Ho Fai Po, Chi Ho Yeung
Coordination of vehicle routes is a feasible way to ease traffic congestions amid a fixed road infrastructure. Nevertheless, even the optimal route configurations are provided to i…
A high-frequency mobility big-data reveals how COVID-19 spread across professions, locations and age groups
Chen Zhao, Jialu Zhang, Xiaoyue Hou +2
As infected and vaccinated population increases, some countries decided not to impose non-pharmaceutical intervention measures anymore and to coexist with COVID-19. However, we do…
Understanding the stochastic dynamics of sequential decision-making processes: A path-integral analysis of multi-armed bandits
Bo Li, Chi Ho Yeung
The multi-armed bandit (MAB) model is one of the most classical models to study decision-making in an uncertain environment. In this model, a player chooses one of possible arm…
Bilevel optimization in flow networks: A message-passing approach
Bo Li, David Saad, Chi Ho Yeung
Optimizing embedded systems, where the optimization of one depends on the state of another, is a formidable computational and algorithmic challenge, that is ubiquitous in real worl…
Scalable Node-Disjoint and Edge-Disjoint Multi-wavelength Routing
Yi-Zhi Xu, Ho Fai Po, Chi Ho Yeung +1
Probabilistic message-passing algorithms are developed for routing transmissions in multi-wavelength optical communication networks, under node and edge-disjoint routing constraint…
