Let us suppose we know that target variable can only be positive and decide to learn prediction function of type ????(). Remember ???? ? = ? if ? ≥ 0 and ???? ? = 0 if ? < 0. Show that MSE of this predictor is not a quadratic form. We decided to use gradient descent algorithm to find w that minimizes MSE of this predictor. Derive the update formula in a vector form. EXTRA CREDIT: Show that MSE for this predictor has the global minimum (i.e, show that MSE is a convex function)
