Derivation of gradient of SVM loss - Mathematics Stack Exchange

Web27 Sep 2024 · In Keras the loss function can be used as follows: def lovasz_softmax (y_true, y_pred): return lovasz_hinge (labels = y_true, logits = y_pred) model. compile (loss = lovasz_softmax, optimizer = optimizer, metrics = [pixel_iou]) Combinations. It is also possible to combine multiple loss functions. The following function is quite popular in … Web28 Nov 2024 · The loss is sum of individual losses. Thus, because differentiation is linear, the gradient of a sum equals sum of gradients, so we can write total derivative = ∑ ( I ( s o m e t h i n g − w y ∗ x i > 0) ∗ ( − x i)) Now, move the − multiplier from x i to the beginning of the formula, and you will get your expression.

WebTo be precise, the SVM classifier uses the hinge loss, or also sometimes called the max-margin loss. The Softmax classifier uses the cross-entropy loss . The Softmax classifier gets its name from the softmax function , which is used to squash the raw class scores into normalized positive values that sum to one, so that the cross-entropy loss can be applied.
