Materials-Discovery Workflows Guided by Symbolic Regression: Identifying Acid-Stable Oxides for Electrocatalysis

1 code implementation8 Dec 2024 Akhil S. Nair, Lucas Foppa, Matthias Scheffler

The efficiency of active learning (AL) approaches to identify materials with desired properties relies on the knowledge of a few parameters describing the property.

Active Learning Symbolic Regression

Accelerating the Training and Improving the Reliability of Machine-Learned Interatomic Potentials for Strongly Anharmonic Materials through Active Learning

no code implementations18 Sep 2024 Kisung Kang, Thomas A. R. Purcell, Christian Carbogno, Matthias Scheffler

Molecular dynamics (MD) employing machine-learned interatomic potentials (MLIPs) serve as an efficient, urgently needed complement to ab initio molecular dynamics (aiMD).

Active Learning

From Prediction to Action: Critical Role of Performance Estimation for Machine-Learning-Driven Materials Discovery

no code implementations27 Nov 2023 Mario Boley, Felix Luong, Simon Teshuva, Daniel F Schmidt, Lucas Foppa, Matthias Scheffler

Materials discovery driven by statistical property models is an iterative decision process, during which an initial data collection is extended with new data proposed by a model-informed acquisition function--with the goal to maximize a certain "reward" over time, such as the maximum property value discovered so far.

Gaussian Processes

Materials genes of heterogeneous catalysis from clean experiments and artificial intelligence

no code implementations16 Feb 2021 Lucas Foppa, Luca M. Ghiringhelli, Frank Girgsdies, Maike Hashagen, Pierre Kube, Michael Hävecker, Spencer J. Carey, Andrey Tarasov, Peter Kraus, Frank Rosowski, Robert Schlögl, Annette Trunschke, Matthias Scheffler

Heterogeneous catalysis is an example of a complex materials function, governed by an intricate interplay of several processes, e. g., the different surface chemical reactions, and the dynamic re-structuring of the catalyst material at reaction conditions.

TCMI: a non-parametric mutual-dependence estimator for multivariate continuous distributions

1 code implementation30 Jan 2020 Benjamin Regler, Matthias Scheffler, Luca M. Ghiringhelli

Mutual information determines the relevance of features in terms of their joint mutual dependence to the property of interest.
