1 and (1-hθ(xi)) is the probability of class 0. Example: def binary_cross_entropy(actual, predicted): sum_score = 0.0 for i in range(len(actual)): sum_score += actual[i] * log(1e-15 + predicted[i]) mean_sum_score = 1.0 / len(actual) * sum_score return -mean_sum_score Hinge Loss The hinge loss is an
