Course Description:
Course description
Many health related problems are difficult to identify. One reason for this difficulty is the multidimensionality of diseases that prevents a simple characterization of the underlying physiological phenomena. Also, physicians typically have a very in-depth knowledge in their area of specialty, but many times it is difficult for them to diagnose complex diseases that crosses the classic discipline boundaries. Often, this situation precludes an accurate and timely diagnose.
This lecture focuses in showing current computational intelligence methods, with an special emphasis in graphical models, that can help:
• to make inferences in complex diagnosis scenarios,
• to group diseases and phenotypes to understand relationships among medical specialties, and
• to explore examples in supporting the diagnosis of rare diseases.
Class format
Each class is three hours in length. The course is designed as a lecture-laboratory, with guided in-
class exercises to illustrate topics covered in the lecture, as they are covered. We will also discuss
one paper each day, that illustrates the use of an agent-based model in a biomedical domain.
