AIMS AND CONTENT

LEARNING OUTCOMES

- To introduce theory and techniques for architectural design of context-aware telecommunications systems able to provide informative services according to a cognitive paradigm

- To provide a common framework to identify and to describe methodologies and techniques for perception, representation and analysis of contextual multisensorial physical (radio, video, audio, etc.) and virtual signals (e.g.network-based context data))

- To provide a common framework to identify and to describe methodologies and techniques for integrating multisensorial contextual data by using Data Fusion paradigms and techniques

- To provide a common framework for defining behavioral artificial models for context based, adaptive and personalized  decision steps used by cognitive system to address and react with respect to different contextual working situations.

- To show examples and applications of specific techniques within cognitive telecommunication systems by means of description of two main case studies: cognitive radio and multisensor/multimodal cognitive human-machine interfaces in smart spaces.

EXAM DESCRIPTION

Oral Examination (70/100%)

Assigned Project  evaluation (30%)

ASSESSMENT METHODS

Oral will consist of project driven slide presentation. Questions will rely on selected techniques chosen from ones presented in the course for the application case as well as on state of the art analysis approach followed

Project will consist in discussing how proposed techniques can be used in the context of an application selected by the student
