State-Dependent Temperature Control for Langevin Diffusions
Xuefeng Gao, Zuo Quan Xu, Xun Yu Zhou
We study the temperature control problem for Langevin diffusions in the context of non-convex optimization. The classical optimal control of such a problem is of the bang-bang type…
Decentralized Stochastic Gradient Langevin Dynamics and Hamiltonian Monte Carlo
Mert Gürbüzbalaban, Xuefeng Gao, Yuanhan Hu +1
Stochastic gradient Langevin dynamics (SGLD) and stochastic gradient Hamiltonian Monte Carlo (SGHMC) are two popular Markov Chain Monte Carlo (MCMC) algorithms for Bayesian inferen…
Non-Convex Optimization via Non-Reversible Stochastic Gradient Langevin Dynamics
Yuanhan Hu, Xiaoyu Wang, Xuefeng Gao +2
Stochastic Gradient Langevin Dynamics (SGLD) is a powerful algorithm for optimizing a non-convex objective, where a controlled and properly scaled Gaussian noise is added to the st…
Regime Switching Bandits
Xiang Zhou, Yi Xiong, Ningyuan Chen +1
We study a multi-armed bandit problem where the rewards exhibit regime switching. Specifically, the distributions of the random rewards generated from all arms are modulated by a c…
