Objectives
This course provides a set of subjects (topics) that are the core for the Intelligent System area.
Aims:
- To know what characterizes and distinguishes AI and how to apply it.
- To know how to automatically represent, acquire, manipulate and apply knowledge using Computational Systems.
- To develop a small project using AI techniques.
Percentual Distribution: Scientific component: 60%; Technological component: 40%
Learning outcomes and competences
At the end of the course, the student is expected to know how to automatically represent, acquire, manipulate and apply knowledge. Namely, the student should be able to:
- Know how to represent inexact knowledge.
- Compare heuristic and systematic methods in the search for solutions.
- Develop interfaces in Natural Language and inference engines for Expert Systems.
- Get acquainted with inductive and deductive learning algorithms.
Working method
Presencial
Pre-requirements (prior knowledge) and co-requirements (common knowledge)
Knowledge of object-oriented and logic-based programming.

Eligibility for exams
To be admitted to exam, the student must have a grade equal or higher to 37,5% in the frequency evaluation.
Calculation formula of final grade
Frequency evaluation: weight=50% ; minimum=3,75 marks (in a maximum of 10) ; including (% related to the frequency evaluation):
- Assignment’s quality and presentation performance (40%);
- Final Report (10%);
- Interim Report + Intercim work (20%);
- Evaluation during classes: mini-exams (30%)
Test/Exam: weight=50%; minimum=3,75 marks (out of 10) (2h30m test with consultation).
Approval requires a minimum of 3,75 (out of 10) in each of the evaluation components.
Examinations or Special Assignments
One practical assignment and the respective report (weight=50%) and an exam (weight=50%).
To get approved, the student must have a grade equal or higher to 37,5% in each of the evaluation items.
Special assessment (TE, DA, ...)
One practical assignment and the respective report (weight=50%) and an exam (weight=50%).
To be approved, the student must have a grade equal or higher to 37,5% in each of the evaluation items.
Classification improvement
Assignment, exam or both.
Mini-exams' grades are not taken into account for this purpose. Its valuation will be added to the Exam component.
