Description

This tutorial text gives a unifying perspective on machine learning by covering both probabilistic and deterministic approaches -which are based on optimization techniques – together with the Bayesian inference approach, whose essence lies in the use of a hierarchy of probabilistic models.The book 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. Focusing on the physical reasoning behind the mathematics, all the various methods and techniques are explained in depth, supported by examples and problems, giving an invaluable resource to the student and researcher for understanding and applying machine learning concepts. The book builds carefully from the basic classical methods  to  the most recent trends, with chapters written to be as self-contained as possible, 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.

Key Features

  • All major classical techniques: Mean/Least-Squares regression and filtering, Kalman filtering, stochastic approximation and online learning, Bayesian classification, decision trees, logistic regression and boosting methods.
  • The latest trends: Sparsity, convex analysis and optimization, online distributed algorithms, learning in RKH spaces, Bayesian inference, graphical and hidden Markov models, particle filtering, deep learning, dictionary learning and latent variables modeling.
  • Case studies - protein folding prediction, optical character recognition, text authorship identification, fMRI data analysis, change point detection, hyperspectral image unmixing, target localization, channel equalization and echo cancellation, show how the theory can be applied.
  • MATLAB code for all the main algorithms are available on an accompanying website, enabling the reader to experiment with the code.

Readership

University Researchers, R&D engineers, graduate students taking a machine learning course.

    machine learning a bayesian and optimization perspective

    This book explains to the reader an impresive variety of Machine Learning related topics. Most these topics are treated with electrical engineering flavor and some of them from the Bayesian perspective. Furthermore, some topics like sparse representations are not commonly included in ML books .This book includes two chapters on that topic, which is a very interesting thing. This combination of topics makes this book a singular one, worthy to purchase for me. Deep Learning is a very extensie ML topic, which in my opinion is not worthy to compress within a chapter. Probably talking about neural networks and the theory behind their aplications in learning representations is a much better approach. I feel this is much more desirable for the reader of this kind of book to take advantage of the deep knowledge an author like S. Theodoridis posses.
