Lipschitz Bandit Optimization with Improved Efficiency
Xu Zhu
We consider the Lipschitz bandit optimization problem with an emphasis on practical efficiency. Although there is rich literature on regret analysis of this type of problem, e.g.,…
Stochastic Lipschitz Q-Learning
Xu Zhu
In an episodic Markov Decision Process (MDP) problem, an online algorithm chooses from a set of actions in a sequence of trials, where is the episode length, in order to ma…
Supervised Multiscale Dimension Reduction for Spatial Interaction Networks
Shaobo Han, David B. Dunson
We introduce a multiscale supervised dimension reduction method for SPatial Interaction Network (SPIN) data, which consist of a collection of spatially coordinated interactions. Th…
Reducing over-clustering via the powered Chinese restaurant process
Jun Lu, Meng Li, David Dunson
Dirichlet process mixture (DPM) models tend to produce many small clusters regardless of whether they are needed to accurately characterize the data - this is particularly true for…
