Define the loss functions for loss evaluation Define the gradient of the loss functions for backpropagation Note that the losses need to be computed between two vectors Y ERNXP and A₂ ERNXP. In this assignment, we consider a two class classification problem with N = 1. P is the number of training data samples or the number of data samples used in a batch. Please refer to the course notes and lecture for details. The widely used losses are 1. Cross entropy for two class classification 1 C(a₂, y) Σ (y, log(ap) + (1 -y) log(1 - 02.p)) p=1 The gradient of the loss term with respect to a2 is specified by 2. Mean squared error for regression Vaz, C. == C(a₂, y) The gradient of the loss term with respect to ay is specified by = C = 1 Paz p(1-azp) Σlla - yp|l² p=1 -2(a₂p - Yp) P Define the loss functions for loss evaluation Define the gradient of the loss functions for backpropagation Note that the losses need to be computed between two vectors Y ERNXP and A₂ ERNXP.
