WebBecause gradient of the product (2068) requires total change with respect to change in each entry of matrix X, the Xb vector must make an inner product with each vector in that … Web12 hours ago · We present a unified non-local damage model for modeling hydraulic fracture processes in porous media, in which damage evolves as a function of fluid pressure. This setup allows for a non-local damage model that resembles gradient-type models without the need for additional degrees of freedom. In other words, we propose a non-local damage …

WebWhile it is a good exercise to compute the gradient of a neural network with re-spect to a single parameter (e.g., a single element in a weight matrix), in practice this tends to be quite slow. Instead, it is more e cient to keep everything in ma-trix/vector form.
