Machine Learning Algorithms - Second Edition

Summary

In this chapter, we introduced the concept of adaptive systems; they can learn from their experiences and modify their behavior in order to maximize the possibility of reaching a specific goal. Machine learning is the name given to a set of techniques that allow you to implement adaptive algorithms to make predictions and auto-organize input data according to their common features.

The three main learning strategies are supervised, unsupervised, and reinforcement. The first one assumes the presence of a teacher that provides a precise feedback on errors. The algorithm can, therefore, compare its output with the right one and correct its parameters accordingly. In an unsupervised scenario, there are no external teachers, so everything ...
