In backpropagation
WebApr 23, 2024 · The aim of backpropagation (backward pass) is to distribute the total error back to the network so as to update the weights in order to minimize the cost function (loss). WebMar 16, 2024 · 1. Introduction. In this tutorial, we’ll explain how weights and bias are updated during the backpropagation process in neural networks. First, we’ll briefly introduce neural networks as well as the process of forward propagation and backpropagation. After that, we’ll mathematically describe in detail the weights and bias update procedure.
