GP-ConvCNP: Better Generalization for Convolutional Conditional Neural Processes on Time Series Data

1 code implementation9 Jun 2021 Jens Petersen, Gregor Köhler, David Zimmerer, Fabian Isensee, Paul F. Jäger, Klaus H. Maier-Hein

Neural Processes (NPs) are a family of conditional generative models that are able to model a distribution over functions, in a way that allows them to perform predictions at test time conditioned on a number of context points.
