There has been an increasing interest in Machine Learning to introduce inductive bias in predictive models through Physics. Such inductive bias allows a significant reduction in the number of data observations needed for training the model plus allows to increase the generalisation ability of the model at extrapolation tasks.
In latent force models, in particular, we combine differential equations with Gaussian processes by building kernel functions that encode dynamical systems. We have found applications of latent force models in a range of domains that include neural-engineering, robotics, computational biology and more recently in monitoring air pollution (see https://gow.epsrc.ukri.org/NGBOViewGrant.aspx?GrantRef=EP/T00343X/1
Building covariance functions for latent force models is usually a tedious process that involves analytically solving different integration problems. In this project, we will look at recent ideas developed in the kernel literature that automatically build covariance functions and apply and extend those approaches to the domain of latent force models.
This position will be open until filled with preferred starting date in April 2020.
The candidate will be supervised by Dr Mauricio A Álvarez, Lecturer in Machine Learning at the Department of Computer Science, University of Sheffield. Dr Álvarez is well known for his work on Latent Force Models and multi-task learning using Gaussian Processes. More information can be found in the following link https://maalvarezl.github.io/
