Towards Multilevel Modelling of Train Passing Events on the Staffordshire Bridge

no code implementations26 Mar 2024 Lawrence A. Bull, Chiho Jeon, Mark Girolami, Andrew Duncan, Jennifer Schooling, Miguel Bravo Haro

We formulate a combined model from simple units, representing strain envelopes (of each train passing) for two types of commuter train.

Encoding Domain Expertise into Multilevel Models for Source Location

no code implementations15 May 2023 Lawrence A. Bull, Matthew R. Jones, Elizabeth J. Cross, Andrew Duncan, Mark Girolami

Most interestingly, domain expertise and knowledge of the underlying physics can be encoded in the model at the system, subgroup, or population level.

Grassmann Stein Variational Gradient Descent

1 code implementation7 Feb 2022 Xing Liu, Harrison Zhu, Jean-François Ton, George Wynne, Andrew Duncan

Stein variational gradient descent (SVGD) is a deterministic particle inference algorithm that provides an efficient alternative to Markov chain Monte Carlo.

Energy-Based Models for Functional Data using Path Measure Tilting

1 code implementation4 Feb 2022 Jen Ning Lim, Sebastian Vollmer, Lorenz Wolf, Andrew Duncan

Their ability to incorporate domain-specific choices and constraints into the structure of the model through composition make EBMs an appealing candidate for applications in physics, biology and computer vision and various other fields.
