Data Science and Machine Learning

Praise for the first edition:

"In nine succinct but information-packed chapters, the authors provide a logically structured and robust introduction to the mathematical and statistical methods underpinning the still-evolving field of AI and data science."

- Joacim Rockloev and Albert A. Gayle, International Journal of Epidemiology, Volume 49, Issue 6

"This book organizes the algorithms clearly and cleverly. The way the Python code was written follows the algorithm closely-very useful for readers who wish to understand the rationale and flow of the background knowledge."

- Yin-Ju Lai and Chuhsing Kate Hsiao, Biometrics, Volume 77, Issue 4

The purpose of Data Science and Machine Learning: Mathematical and Statistical Methods is to provide an accessible, yet comprehensive textbook intended for students interested in gaining a better understanding of the mathematics and statistics that underpin the rich variety of ideas and machine learning algorithms in data science.

New in the Second Edition

This expanded edition provides updates across key areas of statistical learning:



Monte Carlo Methods: A new section introducing regenerative rejection sampling - a simpler alternative to MCMC.
Unsupervised Learning: Inclusion of two multidimensional diffusion kernel density estimators, as well as the bandwidth perturbation matching method for the optimal data-driven bandwidth selection.
Regression: New automatic bandwidth selection for local linear regression.
Feature Selection and Shrinkage: A new chapter introducing the klimax method for model selection in high-dimensions.
Reinforcement Learning: A new chapter on contemporary topics such as policy iteration, temporal difference learning, and policy gradient methods, all complete with Python code.
Appendices: Expanded treatment of linear algebra, functional analysis, and optimization that includes the coordinate-descent method and the novel Majorization-Minimization method for constrained optimization.
