WebIn GPyTorch, defining a GP involves extending one of our abstract GP models and defining a forward method that returns the prior. For deep GPs, things are similar, but there are two abstract GP models that must be overwritten: one for hidden layers and one for the deep GP model itself. In the next cell, we define an example deep GP hidden layer. WebMar 8, 2024 · Much like scikit-learn's gaussian_process module, GPy provides a set of classes for specifying and fitting Gaussian processes, with a large library of kernels that can be combined as needed. GPflow is a re-implementation of the GPy library, using Google's popular TensorFlow library as its computational backend. The main advantage of this …
