Model building is based on a comparison of actual results with the predicted results. The naming conventions are different. The main difference between the hinge loss and the cross entropy loss is that the former arises from trying to maximize the margin between our decision boundary and data points - thus attempting to ensure that each point is correctly and confidently classified*, while the latter comes from a maximum likelihood estimate of our model's parameters. to your account. Hi @wenfeixiang1991 , so you just assigned a different value for label with probability of 0.5 then your model worked better? For a better experience, please enable JavaScript in your browser before proceeding. Why is proving something is NP-complete useful, and where can I use it? The cross-entropy loss does not depend on what the values of incorrect class probabilities are. Used [SEP] to separate the two sentences instead of using separate embeddings via 2 BERT layers. Right now, if \cdot is a dot product and y and y_hat have the same shape, than the shapes do not match. To decrease the number of false positives, set \(\beta < 1\).
