Bayesian risk
WebI Bayes error, also called Bayes risk, is defined as inf f E[L(Y;f(X))] (from now on, for simplicity of notation, we restrict the loss function to be a metric between Y and f(X), although considering a more general loss function is the same). I If f achieves the Bayes error, then f is called a Bayes rule so R(f) (abbreviated as R) is the Bayes ...
