The course shows in detail two kind of Machine Learning techniques. The first part is devoted to Supervised Learning, and the second one to Experiential Learning. In the first part of the course the principles and challenges of Supervised Machine Learning will be analysed. Different kind of classification techniques (Bayesian, rule-based and statistical) will be studied. Also linear regression models will be explained. The use of diverse classification techniques will be analysed, and some methods will be detailed (random forests, etc.). Finally, some advanced topics in classification techniques will be discussed.Regarding the second part of the course, the basic components of the CBR reasoning cycle will be carefully studied and analysed. The application of CBR to the real world will be reviewed, and main problems the deployment of CBR application will be outlined.

Metodología docente

The teaching methodology will include both theoretical lecture sessions, sessions with practical examples of the concepts and algorithms explained in the course, and also some sessions devoted to support the practical work of the students.

Método de evaluación

Evaluation of the knowledge and skills obtained by the students will be assessed through three project works. The first two works (PW1 and PW2) will be on an individual basis and the third one (PW3) will be on a team group basis.

The individual works will consist on the implementation, application and evaluation of some supervised machine learning algorithms
The teamgroup work will consist on the design, implementation, application and validation of a Case-Based Reasoning project to solve a synthetical problem

The final grade will be computed as follows:

FinalGrade= 0.25 * PW1 + 0.25 * PW2 + 0.5 * PW3 * WFstud,
where 0 ≤ WFstud ≤ 1.2

WFstud is a Working Factor evaluating the work of a particular student within his/her teamwork in PW3. It will be obtained by observing and assessing the load of work and degree of participation of each student throughout the PW3. In normal conditions, the WFstud = 1.

The individual works will be evaluated according to the quality of the software developed (0.6), the evaluation done (0.2) and the documentation delivered (0.2).

The Teamgroup work wil be evaluated according to:
- The methodology of the work (0.4)
- The quality of the report written (0.2)
- The quality of the oral exposition (both presentation and content assessed, as well as the ability to answer questions) (0.2)
- Planification, coordination and management of the team (0.05)
- The individual valoration of each student, including her/his integration level within the teamgroup (0.15)
