Soft l1 loss
WebYou have correctly summarized the 0-1 loss function as effectively looking at accuracy. Your 1's become indicators for misclassified items, regardless of how they were misclassified. Since you have three 1's out of 10 items, your classification accuracy is 70%. Webloss (str or callable, optional) – The loss function can be modified to make the fit robust against outliers, see scipy.optimize.least_squares for details. Only “linear” (default) and …
