On Taking Advantage of Opportunistic Meta-knowledge to Reduce Configuration Spaces for Automated Machine Learning

1 code implementation8 Aug 2022 David Jacob Kedziora, Tien-Dung Nguyen, Katarzyna Musial, Bogdan Gabrys

The automated machine learning (AutoML) process can require searching through complex configuration spaces of not only machine learning (ML) components and their hyperparameters but also ways of composing them together, i. e. forming ML pipelines.

AutoWeka4MCPS-AVATAR: Accelerating Automated Machine Learning Pipeline Composition and Optimisation

1 code implementation21 Nov 2020 Tien-Dung Nguyen, Bogdan Gabrys, Katarzyna Musial

Instead of executing the original ML pipeline to evaluate its validity, the AVATAR evaluates its surrogate model constructed by capabilities and effects of the ML pipeline components and input/output simplified mappings.
