Conoscenze e abilità da conseguire
At the end of the course, the student has the basic knowledge for developing and using tools for sequence and structure analysis of biomolecules and more generally for annotation problems in the genomic era. In particular, the student will be able to: discuss the theoretical basics of some machine learning tools (Neural Networks, Hidden Markov Models); selecting programs for problem solving; writing programs.

Metodi didattici
Lectures, exercises and project development.
Modalità di verifica e valutazione dell'apprendimento
Students will be evaluated both with written tests and a final oral exam. Both methods assess the learning outcome of the course and aim at verifying what the student has acquired in terms of Bioinformatics skills during the theoretical and practical parts of the program developed over the two semesters.
Since the course includes two semesters, a written test at the end of each semester will evaluate whether the student is idoneous to attend the final oral section. Students who do not attend the "in itinere" tests, will be requested to have a final general test before the final oral section.
Before attending the final session of the exam, the student has to provide two written reports on the two tutored practical sections, executed in class. During the final oral assessment, the student is expected to answer questions on all the topics discussed during the course.
