We have mainly focused on squared loss, but there are other interesting losses in machine learning. Consider the following loss function which we denote by 0(z)= max(0,-2). Let S be a training set (x+, y),...,(X",y) where each ri ER" and yi {-1,1}. Consider running stochastic gradient descent (SGD) to find a weight vector w that minimizes L-10(y". w1x). Explain the explicit relationship between this algorithm and the Perceptron algorithm. Recall that for SGD, the update rule when the ith example is picked at random is Wnew = Wold no (y*wz).
