CODE 80563 ACADEMIC YEAR 2023/2024 CREDITS 9 cfu anno 1 BIOENGINEERING 11159 (LM-21) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-INF/06 LANGUAGE English TEACHING LOCATION GENOVA SEMESTER 1° Semester TEACHING MATERIALS AULAWEB OVERVIEW The course intends to provide the basic notions for data and signal analysis with emphasis on application to biology and medicine. AIMS AND CONTENT LEARNING OUTCOMES The course provides students with the essential tools and operational skills for quantitative analysis of data and signals of interest for medicine and biology, on a probabilistic perspective AIMS AND LEARNING OUTCOMES By the end of the course the students will be able to: 1. Design and apply methods of analysis and modelling of data - including temporal data (signals) - of interest for medicine and biology 2. Identify the correct approach (model selection, model identification, data visualization) for a specific data analysis problem 3. Use MATLAB to correctly display and model biomedical data and signals PREREQUISITES There are no formal prerequisites, but the course requires solid foundations in mathematical analysis and linear algebra. TEACHING METHODS The course is organised as a combination of lectures and lab activities. Lectures will focus on theory and methods for data analysis. Lab activities will focus on application to real data analysis problems in the context of bioengineering. SYLLABUS/CONTENT A. Data Analysis and Data Display (wk 1-3) Data types.
