Empirical risk minimization. 1. pattern classification: θ : x → {0, 1}, z = (x, y) ∈ x × {0, 1}, l(θ, (x, y)) = 1[θ(x) 6= y]. empirical risk minimization chooses θ to minimize misclassifications on the sample. 2. density estimation: p is a density, x. erm is maximum likelihood. ∼ p , p , l(θ, z) = − log θ∗ pθ(z). Statistical tests signal & background. the probability to reject a background hypothesis for background events is called the background efficiency: 1. b = g(t; b)dt = ↵. tcut. the probability to accept a signal event as signal is the signal efficiency: s = z g(t; s)dt = 1. tcut.
