Course description

The course provides the theoretical and practical basis for Signal Processing by using Artificial Intelligence based methodologies. In particular, several Machine Learning and Soft Computing techniques will be considered for audio signal processing.

Knowledge and understanding skills
The student should demonstrate the knowledge and the understanding the basics of the Java and Python programming languages. In particular, it should be able to develop and to analyze methodologies and algorithms for processing and streaming of data from audio signals. The student should have the ability to understand new Java language-based software development methodologies and techniques for audio signal based data analysis.

Application skills
The student should demonstrate his/her acquired knowledge for solving real problems in the signal processing field by using the Java or Python languages. It also should demonstrate the ability to develop and to analyze algorithms complexity and software validation by comparing different signal processing and Artificial Intelligence based processing tools. The student should be able to use and to choice libraries and software systems for the principal application areas.

Judgment autonomy
The student should be able to know how to independently evaluate the effectiveness and efficiency of a software application in real cases.

Communication skills
The student must be able to write a report and a presentation on a software application made by using Java or Python languages and Signal Processing, Machine Learning and Soft Computing data processing tools. The application is developed on topical issues in Multimedia data processing and presents moments of group work. For these reasons the student should demonstrate abilties on these themes.

Ability to learn
The student should be able to autonomously deepening Java-specific topics and applications, such as accessing databases and online software repositories, and other modes available from the network. The student should be able to participate in forums for the continuous updating of knowledge in computer science.

Learning assessment

The student should demonstrated the ability to understand new software development methodologies and techniques based on the Java and / or Python language for the analysis and processing of audio signals. It should be able to elaborate a report and a presentation on a software realized using the Java or Python language on real problems concerning the Multimedia systems. An oral interview allow to evaluate the student's ability to deal with issues related to multimedia systems.
The verification procedure is higlighted precisely in the e-learning platform of the Department of Science and Technology. In summary, the verification procedure consists of an individual project (60% of the overall valutation) and an oral test (40% of the overall valutation).
For the positive outcome of the evaluation the positive outcomes of both tests are necessary (project and oral examination).
