When to be Discrete: Analyzing Algorithm Performance on Discretized Continuous Problems

no code implementations25 Apr 2023 André Thomaser, Jacob de Nobel, Diederick Vermetten, Furong Ye, Thomas Bäck, Anna V. Kononova

In this work, we use the notion of the resolution of continuous variables to discretize problems from the continuous domain.

Optimizing Stimulus Energy for Cochlear Implants with a Machine Learning Model of the Auditory Nerve

no code implementations14 Nov 2022 Jacob de Nobel, Anna V. Kononova, Jeroen Briaire, Johan Frijns, Thomas Bäck

In the second part of this paper, the Convolutional Neural Network surrogate model was used by an Evolutionary Algorithm to optimize the shape of the stimulus waveform in terms energy efficiency.

Per-run Algorithm Selection with Warm-starting using Trajectory-based Features

no code implementations20 Apr 2022 Ana Kostovska, Anja Jankovic, Diederick Vermetten, Jacob de Nobel, Hao Wang, Tome Eftimov, Carola Doerr

In contrast to other recent work on online per-run algorithm selection, we warm-start the second optimizer using information accumulated during the first optimization phase.

Explorative Data Analysis of Time Series based AlgorithmFeatures of CMA-ES Variants

no code implementations16 Apr 2021 Jacob de Nobel, Hao Wang, Thomas Bäck

From our analysis, we saw that the features can classify the CMA-ES variants, or the function groups decently, and show a potential for predicting the performance of those variants.
