CARE: Confidence-rich Autonomous Robot Exploration using Bayesian Kernel Inference and Optimization

1 code implementation11 Sep 2023 Yang Xu, Ronghao Zheng, Senlin Zhang, Meiqin Liu, Shoudong Huang

We first utilize Gaussian process (GP) regression to learn a surrogate model to infer the confidence-rich mutual information (CRMI) of querying control actions, then adopt an objective function consisting of predicted CRMI values and prediction uncertainties to conduct Bayesian optimization (BO), i. e., GP-based BO (GPBO).
