Preface

Machine Learning and Metaheuristic Computation represent two rapidly expanding domains within the realm of artificial intelligence, each boasting a vast array of applications in computer science. Machine learning, on one hand, encompasses a variety of deterministic and statistical methodologies designed to extract and interpret information from data. This field primarily focuses on identifying and analyzing patterns, a process crucial for understanding complex datasets. Metaheuristic computation, conversely, deals with optimization techniques that leverage collective insights from multiple search agents. This approach is instrumental in enhancing the precision of locating optimal solutions for diverse problems. While machine learning and metaheuristic computation are traditionally associated with different scientific communities, they share a fundamental reliance on advanced computational paradigms. When integrated, these fields can effectively complement each other, mitigating their individual limitations and amplifying their strengths. This synergy not only bridges the gap between two distinct areas of study but also unlocks new potentials in artificial intelligence research and applications.

Metaheuristic schemes have increasingly been utilized to augment machine learning methods, capitalizing on the fact that many processes of machine learning can be considered as optimization problems. This synergy has catalyzed the rapid development of a variety of classifiers and data analysis techniques. The fusion of machine learning and metaheuristic approaches has led to significant advancements in the field, enabling more sophisticated and effective methods for data identification and analysis. Conversely, machine learning techniques have been instrumental in the design and enhancement of metaheuristic algorithms. During the execution of metaheuristic methods, a substantial amount of data, including agent positions and corresponding objective values, is generated. This data trove offers a wealth of information, often underutilized. However, the application of machine learning techniques to this data has opened new avenues. By analyzing and extracting latent insights from the operational data of metaheuristic methods, Machine learning can significantly enhance the efficiency and effectiveness of these algorithms. This interplay between machine learning and metaheuristic schemes exemplifies a virtuous cycle, where each field informs and improves the other, leading to more refined and powerful computational tools.

This book aims to serve as a vital bridge connecting the communities of machine learning and metaheuristic methods, addressing a significant knowledge gap between these two fields. For enthusiasts and practitioners in machine learning who may not be well-versed in metaheuristic computation, this book is an essential resource. It elucidates that metaheuristic techniques are not merely theoretical constructs but practical tools capable of addressing and solving substantial problems frequently encountered in the realm of machine learning. These insights are particularly beneficial for those looking to expand their toolkit beyond conventional machine learning methodologies. Conversely, for those immersed in the world of metaheuristic computation, the book offers a valuable perspective on how machine learning problems can be effectively reformulated as optimization tasks. This recontextualization is key for metaheuristic practitioners aiming to apply their expertise to the nuanced challenges of machine learning. Overall, the book strives to foster a mutual understanding and collaboration between these two communities, highlighting how their combined strengths can lead to groundbreaking advancements in the field of artificial intelligence.

This book stands out not only for its comprehensive coverage of the most pivotal methods and techniques in machine learning and metaheuristic approaches but also for its extensive inclusion of MATLAB code and practical implementations. This aspect is considered the cornerstone of the book’s value. It acknowledges a crucial truth: even readers with a robust mathematical background may struggle to fully grasp a specific method or algorithm until they see it actualized in code. Implementations in the code serve to dissolve any ambiguities or uncertainties that might arise from theoretical descriptions alone, making the material significantly more accessible and clearer. This approach ensures that the learning process is not just theoretical, but also practical and intuitive. As readers progress through the book, moving from fundamental to more advanced methodologies, the computational focus – exemplified through the implemented code – aids in crystallizing their understanding of the different models. This not only reinforces their mathematical concepts but also provides a hands-on experience that is critical in comprehending and applying machine learning and metaheuristic strategies effectively.

This book uniquely positions itself not just as a reference text, but also as a comprehensive course, offering flexibility in how readers engage with its content. It is structured to allow random access, meaning readers can dive into specific chapters or themes as needed, without necessarily following a linear progression. Unlike other books that focus solely on theory and suggest that readers implement algorithms from scratch in exercises, this book takes a different approach. Drawing from our teaching experience, we’ve found that students learn more rapidly and effectively when they have access to existing code that they can modify and experiment with. This practical, hands-on methodology is central to our book’s design.

Many books in the field of machine learning and metaheuristic optimization are crafted with an audience that has advanced training in mathematical sciences in mind. However, after a thorough review of several related texts, it became evident that there is a demand for a more inclusive approach that caters to a wider array of readers and students. Recognizing this gap, the proposed book aims to bridge it by offering a broader and less technically dense exploration of these subjects. While it covers many of the same topics found in other works, this book shifts the focus towards a more accessible presentation. Emphasis is placed on the description, implementation, and practical application of methods rather than delving deeply into the mathematical intricacies. This approach makes the book more approachable for those who may not have a strong background in mathematics, broadening its appeal and utility. It aims to demystify complex concepts and make the fascinating world of machine learning and metaheuristic optimization accessible to a more diverse readership, encouraging engagement and learning across a broader spectrum of individuals.

To start learning machine learning and metaheuristic methods can be overwhelming considering the great number of mathematical concepts and computational techniques. Some very practical books try to satisfy this question by providing chapters where they indicate how to use off-the-shelf recipes for toy problems. However, what happens if some assumptions of the black-box model are not fulfilled. Is it possible to trust its results? Under such conditions, it is necessary to modify or adapt the model. To do this, it is important that a book provides the conceptual tools to appreciate and identify the underlying mathematics. The objective of this book is to be in the middle point, which means to give a rigorous but accessible vision of most of the machine learning algorithms and the most popular approaches of metaheuristic optimization.

Despite the advanced mathematical concepts underpinning machine learning and metaheuristic methods, it is entirely feasible to optimize systems or train models without an in-depth understanding of matrix algebra and calculus. For numerous readers, engaging with machine learning and metaheuristic techniques through programming rather than through complex mathematical formulations presents a more achievable goal. This approach aligns precisely with one of the key objectives of this book: to utilize MATLAB as a means to inspire readers to seamlessly integrate machine learning and optimization systems into their work. The strategy is to introduce and incorporate mathematical concepts only as necessary, easing the reader into the theoretical aspects without overwhelming them from the outset. This methodology not only makes the subject matter more accessible but also demonstrates the practical application of these concepts, thereby demystifying the process and encouraging a broader audience to delve into the fascinating world of machine learning and metaheuristics with confidence and curiosity.

Written from a teaching perspective, this book is primarily designed to function as a comprehensive textbook for undergraduate and postgraduate students specializing in science, electrical engineering, or computational mathematics.
