1. Logistic regression with ±1 labels. Logistic regression (with ±1 labels) maximizes the likelihood L(βο,β) = Π P(X;) Π (1 - p(X;)), = i:Y₁=1 i:Y₁=-1 1 e³o+BTI = 1+e-(Bo+BT) 1+eBo+3x p(x) = Show that this is equivalent to minimizing the cost function n l(Bo, B) = log(1 + exp(-Yi (Bo + BTX₂))). i=1 Hint: Maximizing the likelihood is equivalent to minimizing the negative log-likelihood.
