WebIn this work we develop an original algorithmic approach that, for a family of loss functions that includes squared error and spherical softmax, can compute the exact loss, gradient update for the output weights, and gradient for backpropagation, all in O(d2) O ( d 2) per example instead of O(Dd) O ( D d), remarkably without ever computing the … WebFor the softmax case, this follows trivially from the fact that the exponential function is increasing. For the sparsemax, we use a proof by contradiction. Suppose zi ≤ zj and sparsemaxi(z) > sparsemaxj(z). From the definition in Eq. , we must have ∥p− z∥2 ≥ ∥sparsemax(z)−z∥2, for any p ∈ ΔK−1. tema maal hijrah 2022
