This book introduces readers to Bayesian optimization, highlighting advances in the field and showcasing its successful applications to computer experiments. R code is available as online supplementary material for most included examples, so that readers can better comprehend and reproduce methods. Compact and accessible, the volume is broken down into four chapters. Chapter 1 introduces the reader to the topic of computer experiments; it includes a variety of examples across many industries. Chapter 2 focuses on the task of surrogate model building and contains a mix of several different surrogate models that are used in the computer modeling and machine learning communities. Chapter 3 introduces the core concepts of Bayesian optimization and discusses unconstrained optimization. Chapter 4 moves on to constrained optimization, and showcases some of the most novel methods found in the field. This will be a useful companion to researchers and practitioners working with computer experiments and computer modeling. Additionally, readers with a background in machine learning but minimal background in computer experiments will find this book an interesting case study of the applicability of Bayesian optimization outside the realm of machine learning.

This volume brings together the main results in the field of Bayesian Optimization (BO), focusing on the last ten years and showing how, on the basic framework, new methods have been specialized to solve emerging problems from machine learning, artificial intelligence, and system optimization. It also analyzes the software resources available for BO and a few selected application areas. Some areas for which new results are shown include constrained optimization, safe optimization, and applied mathematics, specifically BO's use in solving difficult nonlinear mixed integer problems. The book will help bring readers to a full understanding of the basic Bayesian Optimization framework and gain an appreciation of its potential for emerging application areas. It will be of particular interest to the data science, computer science, optimization, and engineering communities.

This book describes methods for designing and analyzing experiments that are conducted using a computer code, a computer experiment, and, when possible, a physical experiment. Computer experiments continue to increase in popularity as surrogates for and adjuncts to physical experiments. Since the publication of the first edition, there have been many methodological advances and software developments to implement these new methodologies. The computer experiments literature has emphasized the construction of algorithms for various data analysis tasks (design construction, prediction, sensitivity analysis, calibration among others), and the development of web-based repositories of designs for immediate application. While it is written at a level that is accessible to readers with Masters-level training in Statistics, the book is written in sufficient detail to be useful for practitioners and researchers. New to this revised and expanded edition: • An expanded presentation of basic material on computer experiments and Gaussian processes with additional simulations and examples • A new comparison of plug-in prediction methodologies for real-valued simulator output • An enlarged discussion of space-filling designs including Latin Hypercube designs (LHDs), near-orthogonal designs, and nonrectangular regions • A chapter length description of process-based designs for optimization, to improve good overall fit, quantile estimation, and Pareto optimization • A new chapter describing graphical and numerical sensitivity analysis tools • Substantial new material on calibration-based prediction and inference for calibration parameters • Lists of software that can be used to fit models discussed in the book to aid practitioners

Computer simulation experiments are essential to modern scientific discovery, whether that be in physics, chemistry, biology, epidemiology, ecology, engineering, etc. Surrogates are meta-models of computer simulations, used to solve mathematical models that are too intricate to be worked by hand. Gaussian process (GP) regression is a supremely flexible tool for the analysis of computer simulation experiments. This book presents an applied introduction to GP regression for modelling and optimization of computer simulation experiments. Features: • Emphasis on methods, applications, and reproducibility. • R code is integrated throughout for application of the methods. • Includes more than 200 full colour figures. • Includes many exercises to supplement understanding, with separate solutions available from the author. • Supported by a website with full code available to reproduce all methods and examples. The book is primarily designed as a textbook for postgraduate students studying GP regression from mathematics, statistics, computer science, and engineering. Given the breadth of examples, it could also be used by researchers from these fields, as well as from economics, life science, social science, etc.

Bayesian optimization, a framework for global optimization of expensive-to-evaluate functions, has recently gained popularity in machine learning and global optimization because it can find good feasible points with few function evaluations. In this dissertation, we present novel Bayesian optimization algorithms for problems with parallel function evaluations and multiple information sources, for use in machine learning, biochemistry, and aerospace engineering applications. First, we present a novel algorithm that extends expected improvement, a widely-used Bayesian optimization algorithm that evaluates one point at a time, to settings with parallel function evaluations. This algorithm is based on a new efficient solution method for finding the Bayes-optimal set of points to evaluate next in the context of parallel Bayesian optimization. The author implemented this algorithm in an open source software package co-developed with engineers at Yelp, which was used by Yelp and Netflix for automatic tuning of hyperparameters in machine learning algorithms, and for choosing parameters in online content delivery systems based on evaluations in A/B tests on live traffic. Second, we present a novel parallel Bayesian optimization algorithm with a worst-case approximation guarantee applied to peptide optimization in biochemistry, where we face a large collection of peptides with unknown fitness prior to experimentation, and our goal is to identify peptides with a high score using a small number of experiments. High scoring peptides can be used for biolabeling, targeted drug delivery, and self-assembly of metamaterials. This problem has two novelties: first, unlike traditional Bayesian optimization, where the objective function has a continuous domain and real-valued output well-modeled by a Gaussian Process, this problem has a discrete domain, and involves binary output not well-modeled by a Gaussian process; second, it uses hundreds of parallel function evaluations, which is a level of parallelism too large to be approached with other previously-proposed parallel Bayesian optimization methods. Third, we present a novel Bayesian optimization algorithm for problems in which there are multiple methods or "information sources" for evaluating the objective function, each with its own bias, noise and cost of evaluation. For example, in aerospace engineering, to evaluate an aircraft wing design, different computational models may simulate performance. Our algorithm explores the correlation and model discrepancy of each information source, and optimally chooses the information source to evaluate next and the point at which to evaluate it. We describe how this algorithm can be used in general multi information source optimization problems, and also how a related algorithm can be used in "warm start" problems, where we have results from previous optimizations of closely related objective functions, and we wish to leverage these results to more quickly optimize a new objective function.
