Hyperparameter Selection in Continual Learning

no code implementations9 Apr 2024 Thomas L. Lee, Sigrid Passano Hellan, Linus Ericsson, Elliot J. Crowley, Amos Storkey

In continual learning (CL) -- where a learner trains on a stream of data -- standard hyperparameter optimisation (HPO) cannot be applied, as a learner does not have access to all of the data at the same time.

Data-driven Prior Learning for Bayesian Optimisation

1 code implementation24 Nov 2023 Sigrid Passano Hellan, Christopher G. Lucas, Nigel H. Goddard

We replace this assumption with a weaker one only requiring the shape of the optimisation landscape to be similar, and analyse the recent method Prior Learning for Bayesian Optimisation - PLeBO - in this setting.

Obeying the Order: Introducing Ordered Transfer Hyperparameter Optimisation

1 code implementation29 Jun 2023 Sigrid Passano Hellan, Huibin Shen, François-Xavier Aubet, David Salinas, Aaron Klein

We introduce ordered transfer hyperparameter optimisation (OTHPO), a version of transfer learning for hyperparameter optimisation (HPO) where the tasks follow a sequential order.

Bayesian Optimisation Against Climate Change: Applications and Benchmarks

1 code implementation7 Jun 2023 Sigrid Passano Hellan, Christopher G. Lucas, Nigel H. Goddard

Bayesian optimisation is a powerful method for optimising black-box functions, popular in settings where the true function is expensive to evaluate and no gradient information is available.

Bayesian Optimisation for Active Monitoring of Air Pollution

no code implementations15 Feb 2022 Sigrid Passano Hellan, Christopher G. Lucas, Nigel H. Goddard

Air pollution is one of the leading causes of mortality globally, resulting in millions of deaths each year.
