If a subset of samples all have the same label, then impurity is zero because we cannot make a wrong guess. ...

Witryna1 lut 2024 · From a machine learning perspective, there are two fundamental differences between causal trees and predictive trees. First of all, the target is the treatment effect, which is an inherently unobservable object. Second, we are interested in doing inference, which means quantifying the uncertainty of our estimates. incident in tallaght
