Zusammenfassung: Intro -- Preface -- Acknowledgments -- Introduction -- Scope and Plan -- Historical Perspective -- Machine Learning -- An Overview -- Bias vs. Variance Problem -- Toolboxes -- No Free Lunch Theorems -- References -- Materials Representations -- Conditions for a Valid Representation -- Hierarchy of Materials Representations -- Microscopic Representations -- Mesoscopic Representations -- Macroscopic Representations -- References -- Learning with Large Databases -- Databases -- Experimental Databases -- Computational Databases -- Combined Databases -- Materials Design and DiscoveryZusammenfassung: Machine learning methods are changing the way we design and discover new materials. This book provides an overview of approaches successfully used in addressing materials problems (alloys, ferroelectrics, dielectrics) with a focus on probabilistic methods, such as Gaussian processes, to accurately estimate density functions. The authors, who have extensive experience in this interdisciplinary field, discuss generalizations where more than one competing material property is involved or data with differing degrees of precision/costs or fidelity/expense needs to be consideredZusammenfassung: Multivariate Gaussian Distributions -- Gaussian Processes -- Regression -- Classification -- References -- Authors' Biographies -- Blank PageZusammenfassung: Pareto Optimality -- Pareto Front -- Designing Materials Using Multi-Objective Optimization Strategies -- Multi-Objective Optimization Based on Forward and Inverse Modeling -- Multi-Objective Optimization Based on Optimal Learning -- References -- Multi-Fidelity Learning -- Kriging -- Co-Kriging -- Recursive Co-Kriging -- Multi-Fidelity Learning for Materials Design and Discovery -- References -- Some Closing Thoughts -- The Bayesian Perspective -- Tensors not Tables of Data -- Machine Learning in Experiment -- References -- Basic Notions of Probability TheoryZusammenfassung: Substitution Probability Analysis -- T = 0 vs. T 0 K -- Ensemble Methods Based on Decision Trees -- Decision Trees -- Bagging and Random Forests -- Boosting and Gradient Tree Boosting -- Cross-Validation, Relative Feature Importance, and Partial Dependencies -- References -- Learning with Small Databases -- Background -- Bayes Theorem -- Gaussian Processes -- Applications -- Bayesian Global Optimization -- Examples of Utility Functions -- Applications to Materials Science -- References -- Multi-Objective Learning -- Introduction -- Definitions and Key Concepts -- Pareto DominancePPN: PPN: 1755158718Package identifier: Produktsigel: BSZ-4-NLEBK-KAUB | ZDB-4-NLEBK
