150 Machine Learning, Statistics, and Maths Articles

Home | About the Author | Newsletter | Our Catalog | Free Books | Contact Us

You will find here articles and tutorials that I published between 2017 and 2021, covering original, off-the-beaten-path content in machine learning, operations research, statistics, dynamical systems, mathematics and related topics. The emphasis is on applications, the style is compact, and many illustrations are provided. Concepts are explained in simple English, avoiding jargon and arcane theories.
