Machine Learning for Safety Systems
Course Description and Motivation
The course objective is to provide a general overview of the modern techniques of Machine Learning and their applicability to safety systems. In addition to the description of the foundations of Machine Learning, the course provides the necessary background in order to understand and apply Machine Learning approaches to classification, regression and clustering techniques to solve practical problems in different applicative scenarios by mean of neural networks and other learning techniques. During the course, it will also describe the use of specific software packages, such as WEKA, for the implementation, use and validation of the modern Machine Learning techniques. At the end of the course students will be able to handle different Machine Learning models, to tune them to specific applications, and to design approaches that may scale with large amount of data.
Knowledge and understanding: to know the problems, methodologies and applications of Machine Learning techniques.
Applying knowledge and understanding: to implement different classification, regression and clustering algorithms to solve problems in different applicative scenarios.
Making judgements: to develop adequate critical skills through practical activities in implementing peculiar simulative algorithms and interpreting the obtained results.
Communication skills: to improve ability to critically expose the matters learned during the course.
Learning skills: to improve autonomous and independent study capacity.
