Machine learning is the ability of a machine to expand its knowledge without human intervention. The concept of machine learning is used in software engineering, in data mining, and, in particular, in artificial intelligence. Starting from a knowledge base rich in information, an automatic learning system searches and extracts any regularity between data through data mining techniques. Machine learning algorithms use mathematical-computational methods to learn information directly from the data, without mathematical models and predetermined equations.

The applications of machine learning are already numerous today, some of which have commonly entered our daily life without us realizing it. For example, search engines, through one or more keywords, return lists of results. Spam filters of emails continuously learn both to intercept suspicious or fraudulent...
