Machine learning algorithms make significant use of linear algebra and optimization techniques. Describing the concept and the implementation of linear algebra, calculus, and optimization algorithms in detail would have added significant complexity to the book and distracted the reader from the essence of machine learning.
The appendix lists a basic set of elements of linear algebra and optimization mentioned throughout the book. It also summarizes the coding practices and acquaints the reader with basic knowledge of financial analysis.
Here is a partial list of coding practices and design techniques used throughout the book.
The precompiled Scala for Machine Learning code is ...
