High-Dimensional Data Analysis with Low-Dimensional Models: Principles – Computation – and Applications, written by John Wright and Yi Ma, is a comprehensive guide to understanding and analyzing high-dimensional data using low-dimensional models. The book provides a thorough exploration of the principles, computational techniques, and practical applications of low-dimensional models in data analysis.

The explosion of digital data has led to an increase in high-dimensional data, which poses significant challenges in data analysis. The authors address these challenges by presenting the theory and techniques of low-dimensional models, which enable the analysis of high-dimensional data through a reduced set of dimensions. This approach not only facilitates the analysis of complex data but also reduces computational complexity.

The book is divided into three parts, each providing a detailed examination of the principles, computation, and applications of low-dimensional models. In part one, the authors introduce the basic concepts of low-dimensional models, including principal component analysis (PCA), singular value decomposition (SVD), and sparse coding. They provide a rigorous mathematical foundation for these techniques and discuss their applications in data analysis.

Part two focuses on the computational aspects of low-dimensional models. The authors delve into the optimization algorithms that are used to obtain low-dimensional representations of high-dimensional data. They also discuss the implementation of these algorithms in various programming languages, making the book accessible to both theoreticians and practitioners.

Finally, part three covers the applications of low-dimensional models in various fields, including computer vision, image processing, and bioinformatics. The authors provide numerous examples and case studies to demonstrate the effectiveness of low-dimensional models in these domains.

Overall, High-Dimensional Data Analysis with Low-Dimensional Models: Principles – Computation – and Applications is an essential resource for anyone interested in analyzing high-dimensional data. The book provides a comprehensive and accessible introduction to low-dimensional models and their applications, making it an excellent reference for both students and researchers in the field of data analysis.
