The following are last minute news you should be aware of ;-)

 12/03/2012: The course starts today! The schedule has already changed to reduce overlaps

Course Aim & Organization

The course introduces the general principles of Artificial Intelligence and its applications. Two approaches to model building and knowledge representation will be presented: the traditional one, based on symbolic representation of knowledge (e.g., frames, rules, fuzzy logic, ...), and one inspired to biological models (e.g., neural networks and genetic algorithms).

Teachers

The course is composed by a blending of lectures and exercises by the course teacher and the teaching assistant.

• Matteo Matteucci: the course teacher
• Andrea Bonarini: the teaching assistant

Course Program and Schedule

Lectures will cover the following topics:

• Artificial intelligence: problems, approaches and applications
• Models for knowledge representation biologically inspired and adaptive models.
• Machine Learning: supervised methods, unsupervised methods, reinforcement learning.
• Artificial Neural Networks and Genetic Algorithms.
• Knowledge representation techniques: semantic networks, frames, objects, production rules.
• Uncertainty and approximate knowledge representation. Fuzzy systems.
• Knowledge engineering: methods to develop knowledge based systems.
• Knowledge acquisition, conceptualization and modeling.

Lectures are on:

• Monday 8:15-10:15 in room A3.8
• Tuesday 8:15-10:15 in room A4.1

A detailed schedule of the course can be found here; topics are just indicative while days and teachers are correct up to some last minute change (I will notify you by email). Please note that not all Tuesdays and Wednesdays are in!!

Course Evaluation

The course evaluation is performed by a written exam divided in two parts (lasting usually 2.5 hours in total):

1. Topics covered by the course teacher during the course
2. Topics covered by the teaching assistant during the course

Each part will score 16/32 and the exam is passed if the sum of the two parts, after rounding, is at least 18.

As a reference for the exam format you can have a look at the following material from KE:

• Exam given on 03/02/2012
• Exam given on 08/09/2011
• Exam given on 15/07/2011
• Exam given on 29/06/2011

or from the Italian version (Ingegneria della Conoscenza):

• Exam given on 04/02/2010
• Exam given on 09/09/2009
• Exam given on 20/07/2009
• Exam given on 07/07/2009
• Exam given on 28/02/2009
• Exam given on 18/02/2009

Teaching Material

The textbooks used for the course are:

• Neural Networks and Pattern Recognition, C. Bishop, Oxford University Press, 1995
• Reti neuronali e metodi statistici, S. Ingrassia, and C. Davino. 2002.
• An introduction to genetic algorithms, Melanie Mitchell, MIT Press, 1998.
• Fuzzy Logic with Engineering Applications (Third Edition), T. Ross, Wiley, 2010
• Fuzzy Logic: come insegneremo alle macchine a ragionare da uomini, A. G. Pizzaleo, Castelvecchi, Roma.

In the following you can find the lecture slides used by the teacher and the teaching assistant during classes. Some additional material that could be used to prepare the oral examination is provided as well.
