Target Score Matching

no code implementations13 Feb 2024 Valentin De Bortoli, Michael Hutchinson, Peter Wirnsberger, Arnaud Doucet

Denoising Score Matching estimates the score of a noised version of a target distribution by minimizing a regression loss and is widely used to train the popular class of Denoising Diffusion Models.

Estimating Gibbs free energies via isobaric-isothermal flows

1 code implementation22 May 2023 Peter Wirnsberger, Borja Ibarz, George Papamakarios

We present a machine-learning model based on normalizing flows that is trained to sample from the isobaric-isothermal ensemble.

MultiScale MeshGraphNets

no code implementations2 Oct 2022 Meire Fortunato, Tobias Pfaff, Peter Wirnsberger, Alexander Pritzel, Peter Battaglia

In recent years, there has been a growing interest in using machine learning to overcome the high cost of numerical simulation, with some learned models achieving impressive speed-ups over classical solvers whilst maintaining accuracy.

Normalizing flows for atomic solids

1 code implementation16 Nov 2021 Peter Wirnsberger, George Papamakarios, Borja Ibarz, Sébastien Racanière, Andrew J. Ballard, Alexander Pritzel, Charles Blundell

We present a machine-learning approach, based on normalizing flows, for modelling atomic solids.

SyMetric: Measuring the Quality of Learnt Hamiltonian Dynamics Inferred from Vision

1 code implementation NeurIPS 2021 Irina Higgins, Peter Wirnsberger, Andrew Jaegle, Aleksandar Botev

Using SyMetric, we identify a set of architectural choices that significantly improve the performance of a previously proposed model for inferring latent dynamics from pixels, the Hamiltonian Generative Network (HGN).

Autonomous Driving Image Reconstruction

Which priors matter? Benchmarking models for learning latent dynamics

2 code implementations9 Nov 2021 Aleksandar Botev, Andrew Jaegle, Peter Wirnsberger, Daniel Hennes, Irina Higgins

Learning dynamics is at the heart of many important applications of machine learning (ML), such as robotics and autonomous driving.

Targeted free energy estimation via learned mappings

no code implementations12 Feb 2020 Peter Wirnsberger, Andrew J. Ballard, George Papamakarios, Stuart Abercrombie, Sébastien Racanière, Alexander Pritzel, Danilo Jimenez Rezende, Charles Blundell

Here, we cast Targeted FEP as a machine learning problem in which the mapping is parameterized as a neural network that is optimized so as to increase overlap.

Infinitely Deep Infinite-Width Networks

no code implementations ICLR 2019 Jovana Mitrovic, Peter Wirnsberger, Charles Blundell, Dino Sejdinovic, Yee Whye Teh

Infinite-width neural networks have been extensively used to study the theoretical properties underlying the extraordinary empirical success of standard, finite-width neural networks.
