WebAug 13, 2024 · The idea behind best subset selection is choose the “best” subset of variables to include in a model, looking at groups of variables together as opposed to step-wise regression which compares them one at a time. We determine which set of variables are “best” by assessing which sub-model fits the data best while penalizing for the … WebMachine teaching is the control of machine learning. The machine learning algorithm defines a dynamical system where the state (i.e. model) is driven by training data. Machine teaching designs the optimal training data to drive the learning algorithm to a target model.
