Week 9: Latent Force Models

[Powerpoint][jupyter][google colab][reveal][edit]

Abstract: null

Gaussian Process Summer School notebook setup

We install packages used across the notebooks for data loading, plotting helpers, and Gaussian process modelling.

import importlib.util

cmd = install_command('pods')

%system {cmd}

cmd = install_command('notutils')

%system {cmd}

cmd = install_command('mlai')

%system {cmd}

cmd = install_command('GPy')

%system {cmd}

GPy: A Gaussian Process Framework in Python

Gaussian processes are a flexible tool for non-parametric analysis with uncertainty. The 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. We welcome contributions which can be made through the GitHub repository https://github.com/SheffieldML/GPy

GPy 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 GitHub and the team welcomes contributions.

The aim for GPy is to be a probabilistic-style programming language, i.e., you specify the model rather than the algorithm. As well as a large range of covariance functions the software allows for non-Gaussian likelihoods, multivariate outputs, dimensionality reduction and approximations for larger data sets.

The documentation for GPy can be found here.
