Web15 apr. 2024 · In this section we first discuss the generation of training data \(D_{train}\) comprising pairs of values of design input, and the probability for Y to be 1 at that design temperature. As motivated above, we will undertake this generation in two distinct ways - for the \(D_{train}\) generated under a given approach, we refer to it by its updated name. http://cbonnett.github.io/MDN_EDWARD_KERAS_TF.html
