This section explains the different kinds of machine learning algorithms, such as unsupervised machine learning algorithms and traditional supervised learning algorithms, in detail and also introduces us to algorithms for natural language processing. The section ends with introducing us to recommendation engines. The chapters included in this section are:

• Chapter 6, Unsupervised Machine Learning Algorithms 
• Chapter 7, Traditional Supervised Learning Algorithms
• Chapter 8, Neural Network Algorithms
• Chapter 9, Algorithms for Natural Language Processing
• Chapter 10, Recommendation Engines
