Black-Box Optimization Revisited: Improving Algorithm Selection Wizards through Massive Benchmarking [article]

Laurent Meunier, Herilalaina Rakotoarison, Pak Kan Wong, Baptiste Roziere, Jeremy Rapin, Olivier Teytaud, Antoine Moreau, Carola Doerr
2021 arXiv   pre-print
We demonstrate the advantages of such a broad collection by deriving from it Automated Black Box Optimizer (ABBO), a general-purpose algorithm selection wizard.  ...  Existing studies in black-box optimization for machine learning suffer from low generalizability, caused by a typically selective choice of problem instances used for training and testing different optimization  ...  A New Algorithm Selection Wizard: NGOpt8 Black-box optimization is sometimes dominated by evolutionary computation.  ...

Emergent Solutions to High-Dimensional Multitask Reinforcement Learning

Stephen Kelly, Malcolm I. Heywood
2018 Evolutionary Computation  
Algorithms that learn through environmental interaction and delayed rewards, or reinforcement learning (RL), increasingly face the challenge of scaling to dynamic, highdimensional, and partially observable  ...  In this work, we propose a framework based on genetic programming which adaptively complexifies policies through interaction with the task.  ...  Black diamonds denote the most complex cases, with text indicating the cumulative number of operations required to train each algorithm up to that point.  ...

IMAGINATION FROM EVALUATION [article]

Frank Ulrich
2016 Ph.d.-serien for Det Teknisk-Naturvidenskabelige Fakultet, Aalborg Universitet  
Karlstown went from a period of the mobile technology idea being relatively stable, "black boxed", and rejected to see it remerge from its "black box" state in a neoteric form, changing human actors' perspective  ...  Hence, ideas stay "black boxed" until human actors enact them once again due to new input .  ...  Through this unit of analysis, we gain new insights into creative information systems artifacts, how new artifact components can be theorized, and ultimately, how artifacts can be improved.  ...
