Stitching for Neuroevolution: Recombining Deep Neural Networks without Breaking Them

no code implementations21 Mar 2024 Arthur Guijt, Dirk Thierens, Tanja Alderliesten, Peter A. N. Bosman

To correct for differing feature representations between these layers we employ stitching, which merges the networks by introducing new layers at crossover points.

The Impact of Asynchrony on Parallel Model-Based EAs

no code implementations27 Mar 2023 Arthur Guijt, Dirk Thierens, Tanja Alderliesten, Peter A. N. Bosman

Thus, if an asynchronous parallel MBEA is also affected by an evaluation time bias, this could result in learned models to be less suited to solving the problem, reducing performance.

Solving Multi-Structured Problems by Introducing Linkage Kernels into GOMEA

1 code implementation11 Mar 2022 Arthur Guijt, Dirk Thierens, Tanja Alderliesten, Peter A. N. Bosman

This cannot be modelled sufficiently well when using linkage models that aim at capturing a single type of linkage structure, deteriorating the advantages brought by MBEAs.

EXPObench: Benchmarking Surrogate-based Optimisation Algorithms on Expensive Black-box Functions

1 code implementation8 Jun 2021 Laurens Bliek, Arthur Guijt, Rickard Karlsson, Sicco Verwer, Mathijs de Weerdt

Surrogate algorithms such as Bayesian optimisation are especially designed for black-box optimisation problems with expensive objectives, such as hyperparameter tuning or simulation-based optimisation.

Bayesian Optimisation Benchmarking

Black-box Mixed-Variable Optimisation using a Surrogate Model that Satisfies Integer Constraints

no code implementations8 Jun 2020 Laurens Bliek, Arthur Guijt, Sicco Verwer, Mathijs de Weerdt

A challenging problem in both engineering and computer science is that of minimising a function for which we have no mathematical formulation available, that is expensive to evaluate, and that contains continuous and integer variables, for example in automatic algorithm configuration.
