Syllabus
Course overview and goals
By the end of this course, one will learn about different types of biological signals and their signal processing methods, as well as recent trends in applying the results as medical diagnostics and engineering interfaces. In particular, many topics using brain activity signals will be covered and students will learn to understand the differences in extractable information depending on measurement and processing methods, and how such information can contribute to medicine and society.
Course description and aims
The goal is to learn the types of biological signals and signal processing methods, to understand the contents of the obtainable information, and to acquire thinking that can be used for medical care and society.
Keywords
time-series signal processing, neuroscience, biomedical engineering, machine learning, and brain-machine interfaces
Competencies
- Specialist skills
- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
Class flow
Lecture materials (slides) and exercises will be used to explain the types and mechanisms of biological signals and examples of their application in medicine and engineering. In workshop sessions, students will experience with biosignal-based interface demonstrations, lectures by experts, or presentations on research papers they have searched on their own.
