Announcement: The final test of the Course for the Summer session, that is Second MidTerm Test, First Final Test and the Secondo Final Test, are scheduled according to the following agenda: Second Mid Term test: Friday, June 13th, 2025, at 11:30 in Classroom 10 (Engineering Macroarea), First Final Test: Friday, June 20th, 2025, at 11:00 in Classroom 10 (Engineering Macroarea), Second Final Test: Friday, July 18th, 2025, at 11:00 in Classroom C11 (Engineering Macroarea), Students that decide to participate to the Second Mid Term are excluded from the participation to the First Final Test, as for the short time period that (in case of an insufficient qualification in the Second Mid Term) does not allow a proper recovery. Such students are of course admitted to the Second Final Test. Students with a positive evaluation to the Mid Term 1 can also decide to register directly to the First Final test, and they resign in this way from an evaluation over the Mid Term tests. All students applying for the Summer Session tests are invited to register to the respective exams at the Delphi pages. Announcement: Results of the First MidTerm Test held on April 28th, 2025. Students are invited to write to the Course responsabile for accessing to their own written test. Only admitted students are allowed to register to the second Mid Term (that will be held on June 13, 2025), while the other students are invited to register for Final Test 1 (that will be held on June 20, 2025). Please register to the two distinct exams at the Delphi pages. Announcement: The First MidTerm Test of the course is scheduled on April 28th, 2025, and it will be held in Classroom C10, at 13:00. The test will focus on all the topics discussed during the lessons up to April 17th, 2025. Students are invited to register to the exam at the Delphi pages. News Announcement: The lesson of Thursday April, 3rd will focus on a Lab exercise in the use of SVM and Kernel Learning software on different classification Tasks. Proposed Exercises on HMM modeling.

Teaching materials, such as papers PDFs or slides will be published on this page during the Course activities. The Course refers to research and projects of the Semantics Analytics Group (SAG) that makes research about Deep Learning and Natural Language Processing in the design and engineering of Generative AI systems and complex AI Services. These systems provide predictive and intelligent decision making functionalities document search and interpretation, in the Knowledge Integration and Summarization in the Intellligent Cybersecurity, in the Social Network Analysis and in all processes of Digital Transformation in the industry or in specific domains, such as medicine or banking/fintech. Active experimentations and projects are detailed at SAG Laboratory for Semantics Analytics, that regularly financially supports Applied Research Internships or Laurea Thesis awards.
