Thermodynamic Natural Gradient Descent

no code implementations22 May 2024 Kaelan Donatella, Samuel Duffield, Maxwell Aifer, Denis Melanson, Gavin Crooks, Patrick J. Coles

Second-order training methods have better convergence properties than gradient descent but are rarely used in practice for large-scale training due to their computational overhead.

Exploiting Inductive Biases in Video Modeling through Neural CDEs

no code implementations8 Nov 2023 Johnathan Chiu, Samuel Duffield, Max Hunter-Gordon, Kaelan Donatella, Max Aifer, Andi Gu

We introduce a novel approach to video modeling that leverages controlled differential equations (CDEs) to address key challenges in video tasks, notably video interpolation and mask propagation.

Optical Flow Estimation

A State-Space Perspective on Modelling and Inference for Online Skill Rating

1 code implementation4 Aug 2023 Samuel Duffield, Samuel Power, Lorenzo Rimella

We summarise popular methods used for skill rating in competitive sports, along with their inferential paradigms and introduce new approaches based on sequential Monte Carlo and discrete hidden Markov models.

Bayesian Learning of Parameterised Quantum Circuits

no code implementations15 Jun 2022 Samuel Duffield, Marcello Benedetti, Matthias Rosenkranz

Currently available quantum computers suffer from constraints including hardware noise and a limited number of qubits.

Dimensionality Reduction

Online Particle Smoothing with Application to Map-matching

1 code implementation8 Dec 2020 Samuel Duffield, Sumeetpal S. Singh

We introduce a novel method for online smoothing in state-space models that utilises a fixed-lag approximation to overcome the well known issue of path degeneracy.
