Mastering Machine Learning Algorithms. - Second Edition

By: Giuseppe Bonaccorso

Overview of this book

Mastering Machine Learning Algorithms, Second Edition helps you harness the real power of machine learning algorithms in order to implement smarter ways of meeting today's overwhelming data needs. This newly updated and revised guide will help you master algorithms used widely in semi-supervised learning, reinforcement learning, supervised learning, and unsupervised learning domains. You will use all the modern libraries from the Python ecosystem – including NumPy and Keras – to extract features from varied complexities of data. Ranging from Bayesian models to the Markov chain Monte Carlo algorithm to Hidden Markov models, this machine learning book teaches you how to extract features from your dataset, perform complex dimensionality reduction, and train supervised and semi-supervised models by making use of Python-based libraries such as scikit-learn. You will also discover practical applications for complex techniques such as maximum likelihood estimation, Hebbian learning, and ensemble learning, and how to use TensorFlow 2.x to train effective deep neural networks. By the end of this book, you will be ready to implement and solve end-to-end machine learning problems and use case scenarios.

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.

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)
