Privacy-Preserved Average Consensus Algorithms with Edge-based Additive Perturbations

no code implementations6 Sep 2021 Yi Xiong, Zhongkui Li

In the scrambling phase, each agent is required to generate some perturbation signals and add them to the edges leading out of it.

Debiasing Samples from Online Learning Using Bootstrap

no code implementations31 Jul 2021 Ningyuan Chen, Xuefeng Gao, Yi Xiong

It has been recently shown in the literature that the sample averages from online learning experiments are biased when used to estimate the mean reward.

Sublinear Regret for Learning POMDPs

no code implementations8 Jul 2021 Yi Xiong, Ningyuan Chen, Xuefeng Gao, Xiang Zhou

We study the model-based undiscounted reinforcement learning for partially observable Markov decision processes (POMDPs).

Regime Switching Bandits
