WebThis base Kernel class includes a lengthscale parameter \(\Theta\), which is used by many common kernel functions.There are a few options for the lengthscale: Default: No lengthscale (i.e. \(\Theta\) is the identity matrix). Single lengthscale: One lengthscale can be applied to all input dimensions/batches (i.e. \(\Theta\) is a constant diagonal matrix). WebGPy is a BSD licensed software code base for implementing Gaussian process models in python. This allows GPs to be combined with a wide variety of software libraries. The software itself is available on GitHuband …
