To get the most out of this book

• The reader must possess a basic knowledge of the most common machine learning algorithms, with a clear understanding of their mathematical structure and applications.
• As Python is the language chosen for the example, the reader must be familiar with this language and, in particular, frameworks like scikit-learn, TensorFlow 2, pandas, and PyStan.
• Considering the complexity of some topics, a good knowledge of calculus, probability theory, linear algebra, and statistics is strongly advised.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example, "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

ax[0].set_title('L1 regularization', fontsize=18)
ax[0].set_xlabel('Parameter', fontsize=18)
ax[0].set_ylabel(r'$|\theta_i|$', fontsize=18)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

ax[0].set_title('L1 regularization', fontsize=18)
ax[0].set_xlabel('Parameter', fontsize=18)
ax[0].set_ylabel(r'$|\theta_i|$', fontsize=18)

Any command-line input or output is written as follows:

pip install -U scikit-fuzzy

Bold: Indicates a new term, an important word, or words that you see on the screen, for example, in menus or dialog boxes, also appear in the text like this. For example: "Select System info from the Administration panel."
