WebActive regression ¶. Active regression. In this example, we are going to demonstrate how can the ActiveLearner be used for active regression using Gaussian processes. Since Gaussian processes provide a way to quantify uncertainty of the predictions as the covariance function of the process, they can be used in an active learning setting. [1]:
