Web11 set 2024 · My understanding of SVM is that it's very similar to a logistic regression (LR), i.e. a weighted sum of features is passed to the sigmoid function to get a probability of belonging to a class, but instead of the cross-entropy (logistic) loss function, training is performed using the hinge loss. Web4 set 2024 · probs = probs[:, 1] # calculate log loss. loss = log_loss(testy, probs) In the binary classification case, the function takes a list of true outcome values and a list of probabilities as arguments and calculates the average log loss for the predictions. We can make a single log loss score concrete with an example. the office bachelorette party ideas https://wheatcraft.net
