Automated Model Discovery for Soft Matter Systems
(Drittmittelfinanzierte Einzelförderung)
Projektleitung: ,
Laufzeit: 1. Juli 2024 – 30. Juni 2029
Akronym: DISCOVER
Mittelgeber: EU / European Research CouncilAutomatisierte Modelle bringen Erforschung weicher Materie voran
Weiche Materialien, die sich durch thermische oder mechanische Beanspruchung leicht verformen oder strukturell verändern lassen, sind im modernen Leben unverzichtbar, wobei sie Autonomie, Nachhaltigkeit und Gesundheit beeinflussen. Die genaue Modellierung dieser Materialien ist jedoch komplex und meist nur von wenigen gut ausgebildeten Fachleuten zu bewerkstelligen. Das Ziel des ERC-finanzierten Projekts DISCOVER besteht darin, die konstitutive Modellierung durch automatisierte Modellfindung zugänglicher zu gestalten. Zu den Zielen zählt die Entwicklung neuronaler Netzwerke, die selbstständig die besten Modelle, Parameter und Experimente für verschiedene Systeme der weichen Materie finden. Zudem werden die Forschenden die Leistung des Modells anhand verschiedener Experimente bewerten und bayessche Analysen zur Messung von Unsicherheiten einsetzen. Die automatisierte Modellfindung sollte die Erkundung eines breiten Spektrums von Modellparametern gestatten und Einblicke in Systeme aus weicher Materie bieten, die mit konventionellen Methoden nicht zu realisieren sind.
