Minibatch training of neural network ensembles via trajectory sampling

no code implementations23 Jun 2023 Jamie F. Mair, Luke Causer, Juan P. Garrahan

Most iterative neural network training methods use estimates of the loss function over small random subsets (or minibatches) of the data to update the parameters, which aid in decoupling the training time from the (often very large) size of the training datasets.

Combining Reinforcement Learning and Tensor Networks, with an Application to Dynamical Large Deviations

1 code implementation28 Sep 2022 Edward Gillman, Dominic C. Rose, Juan P. Garrahan

We present a framework to integrate tensor network (TN) methods with reinforcement learning (RL) for solving dynamical optimisation tasks.

Training neural network ensembles via trajectory sampling

no code implementations22 Sep 2022 Jamie F. Mair, Dominic C. Rose, Juan P. Garrahan

In machine learning, there is renewed interest in neural network ensembles (NNEs), whereby predictions are obtained as an aggregate from a diverse set of smaller models, rather than from a single larger model.

Symmetry-induced fluctuation relations in open quantum systems

no code implementations11 Mar 2021 Stefano Marcantoni, Carlos Pérez-Espigares, Juan P. Garrahan

We derive a general scheme to obtain quantum fluctuation relations for dynamical observables in open quantum systems.

A reinforcement learning approach to rare trajectory sampling

1 code implementation26 May 2020 Dominic C. Rose, Jamie F. Mair, Juan P. Garrahan

By minimising the distance between a reweighted ensemble and that of a suitably parametrised controlled dynamics we arrive at a set of methods similar to those of RL to numerically approximate the optimal dynamics that realises the rare behaviour of interest.

A Tensor Network Approach to Finite Markov Decision Processes

no code implementations12 Feb 2020 Edward Gillman, Dominic C. Rose, Juan P. Garrahan

Tensor network (TN) techniques - often used in the context of quantum many-body physics - have shown promise as a tool for tackling machine learning (ML) problems.
