Learning outcomes
At the end of the course, the student acquires advanced machine learning based approaches (Support Vector Machine, Conditional Random Fields, Hybrid methods) to complement previous expertise. Problems of Systems Biology will be introduced with focusing on network theory and dynamic modeling to approach complexity at the cell level. In particular, the student will be able to: - understand and modeling biological complexity; - modeling time evolution of a biological system; - predicting protein-protein interaction and DNA/RNA protein interaction.
