Purpose of supervised statistical learning

The purpose of a statistical learning model is to use a statistical model and the training data to find the function f^\hat{f} as an estimate of the unknown function ff that maps the matrix of input variables XX to the outcome vector YY, as best as possible. Y=f(X)+ϵf^(X)Y = f(X) + \epsilon \approx \hat{f}(X)
