WebJan 21, 2024 · The penalty term is b _2. So to change the quadratic loss on the residual means changing { Ax-b _2}. Is that what you want? That is the case with the hqreg, where the whole loss function is changed to the Huber loss function, you can still add a penalization term to that loss function which would regularize it. WebNov 23, 2024 · The hinge loss is a loss function used for training classifiers, most notably the SVM. Here is a really good visualisation of what it looks like. The x-axis represents the …

It combines the best properties of L2 squared loss and L1 absolute loss by being strongly convex when close to the target/minimum and less steep for extreme values. The scale at which the Pseudo-Huber loss function transitions from L2 loss for values close to the minimum to L1 loss for extreme values and the steepness at extreme values can be controlled by the value.
