Machine Learning: A Bayesian and Optimization Perspective (1st edition)
S. Theodoridis. Book published by Elsevier This book gives a unifying perspective on machine learning by covering both probabilistic and deterministic approaches, together with the Bayesian inference approach. The material presents the major machine learning methods as they have been developed in different disciplines, such as statistics, statistical and adaptive signal processing and computer science. It builds carefully from the basic classical methods to the most recent trends, making the text suitable for different courses: pattern recognition, statistical/adaptive signal processing, statistical/Bayesian learning, as well as short courses on sparse modeling, deep learning, and probabilistic graphical models. (Harris Georgiou: acknowledged for contribution/proof-reading) Elsevier, 1st/edition, ISBN:978-0128015223, 10-Apr-2015. [UoA/S.Theodoridis: book's homepage ]
Transforming Clothing Production into a demand-driven, knowledge-based, high-tech industry - The Leapfrog paradigm
H. Georgiou, G. Kartsounis (members of the team of AUA, subcontractor to Hohenstein Institute, contributing authors). Book published by Springer, regarding advances in nanotechnology and innovative polymeric materials, flexible robotics and innovative joining techniques, 3D CAD and Collaborative Virtual Prototyping, knowledge networking of textile and garment organizations. The book is a collection of short papers from prominent researchers involved with the LEAPFROG (Leadership for European Apparel Production From Research along Original Guidelines) initiative. LEAPFROG proposes a revolutionary industrial paradigm based on research results in scientific-technological fields, outlining key developments in all of the above areas, covering both technological and business aspects. It is an excellent reference for decision makers, managers, scientists and practitioners in the textile and clothing sectors, as well as academics and postgraduate students across a range of disciplines. (results from: LEAPFROG-IP, 6th Framework, FP6-2003-NMP-NI-3, Contract No: 515810). Springer, 1st/edition, ISBN:978-1848826076, 29-Sept-2009. [download: preface/TOC (pdf) from Springer.com]
Pattern Recognition (4th edition)
S. Theodoridis, C. Koutroumbas. Book published by Academic Press, a classic textbook covering classical and current theory and practice, of supervised, unsupervised and semi-supervised pattern recognition, to build a complete background for professionals and students of engineering. The authors, leading experts in the field of pattern recognition, have provided an up-to-date, self-contained volume encapsulating this wide spectrum of information. The very latest topics are incorporated in this edition, including semi-supervised learning, combining clustering algorithms, and relevance feedback.
