WebThe GPy software was started in Sheffield to provide a easy to use interface to GPs. One which allowed the user to focus on the modelling rather than the mathematics. Figure: GPy is a BSD licensed software code base for implementing Gaussian process models in Python. It is designed for teaching and modelling. WebGPy is a Gaussian Process (GP) framework written in python, from the Sheffield machine learning group. Gaussian processes underpin range of modern machine learning algorithms. In GPy, we've used python to implement a range of machine learning algorithms based on GPs. GPy is available under the BSD 3-clause license. how to stop a cat from biting when petting https://mauiartel.com
