===== Course Objectives =====

<WRAP box round 95% center>
KNOWLEDGE AND UNDERSTANDING

The aim of the course is to provide the student with knowledge and skills in the area of machine learning.\\
At the end of the course the student should be able to:

  * distinguish the various machine learning paradigms;
  * know the learning theory
  * know classification algorithms, regression, clustering and dimension reduction;


APPLYING KNOWLEDGE AND UNDERSTANDING\\
After completing the course, the student must demonstrate that he is able to:

  * apply the different machine learning paradigms
  * implement the classification, regression, clustering and dimensionality reduction algorithms;
  * design and implement systems able to learn automatically from real data and situations;


COMMUNICATION SKILLS\\
At the end of this training activity, the student will be able to express himself clearly and with appropriate terms, using the English language, in the learning discussions as well as expose the results of a research concerning technical aspects of machine learning.

LEARNING SKILLS
At the end of this training activity the student will be able to:

  *  Finding and learning the innumerable algorithms and techniques that are presented in the field of machine learning
  *  Implementing and using the new algorithms
