COGNITIVE COMPUTING AND ARTIFICIAL INTELLIGENCE
ING-INF/05 - 9 CFU - 2° Semester
Teaching StaffDANIELA GIORDANO
The course provides an integrated and modern approach to the design and development of intelligent systems, by resorting to state of the art technologies and methods from the fields of machine learning, large-scale multimedia analysis, knowledge representation, logic and automated reasoning to solve typical and topical problems in application scenarios such as: natural human-computer interaction, business intelligence and decision-making support. The students will learn to design, develop and validate systems that learn from heterogeneous data (either in a supervised or unsupervised manner) and are able to detect and recognize patterns; 2) they will learn to program the behaviours of autonomous agents (NAO robots) capable to interact adaptively with humans. The course provides the theoretical foundations of artificial cognitive systems, but it is essentially practical and application-oriented. The students will gather hands-on experience on languages supporting the development of semantic web and logic programming applications, on frameworks and libraries such as TORCH for deep learning; on MATLAB libraries for multimedia signal processing and data mining; and with the NAO autonomous, programmable humanoid robot.
