Provides the basic notions for data and signal analysis and practical applications to biomedical data and signals.
L'insegnamento fornisce gli strumenti essenziali e le competenze operative per l’analisi quantitativa di dati e segnali di interesse per la medicina e la biologia, in una prospettiva probabilistica
The aim of this course is to provide students with the essential tools for quantitative analysis of data and signals of interest for medicine and biology.
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 and effectively visualizing biomedical data and signals and to implement models of them
There are no formal prerequisites, but the course requires solid foundations in mathematical analysis and linear algebra.
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.
In AY 2022-2023 the course will be taught in presence.

Written exam (weight 50%)
Project work (individuals or couples, weight 50%)
• Solution of a real problem of biomedical data analysis/processing, chosen from a list of proposed projects
• Development of software for calculation/analysis/processing
• Interactive application (MATLAB Livescript) reporting the results
• Fixed deadline (early February)
Project work will be assessed in terms of:
1) Documentation (correctess, clarity, synthesis, terminology): 10 pts
2) Implementation (code structure and organization, efficiency): 10 pts
3) Data Visualization (technical quality of figures, adequacy of display technique, efficacy, clarity): 10 pts
4) Bonus (max 2 pts) if the report provides additional analysis (in addition to those required). Bonus is only awarded if maximum score is obtained in the other three criteria.
