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. WebWe present an approach where the VAE reconstruction is expressed on a volumetric grid, and demonstrate how this model can be trained efficiently through a novel backpropagation method that exploits the sparsity of the projection operation in Fourier-space. We achieve improved results on a simulated data set and at least equivalent results on an ...
