The course consists of following subjects: structure of pattern recognition systems, Bayes' theorem; statistical feature extraction; linear discriminant function; and neural networks. We will review actual applications in this area, such as character, voice and image recognition. This course is related to DP1.
The aim of the course is to comprehend the basic structure of pattern recognition systems and pattern recognizers based on Bayes' theorem. We shall learn the following: complexity, discrimination ability and robustness of discrimination functions; structure of parametric recognizer and non-parametric recognizer; and the difference between the two recognizers. Students in this course will obtain skills in applying these methods and techniques to actual problems.
Assessed by the reports. The learners can get feedback from the reports commented by the professor.

This course is the most basic among pattern recognition related subjects in a graduate school. The participants had better learn the image processing and the voice processing at the next stage of this course. The learners should review information algebra, coding theory, probability theory, information theory and mathematical programming.
The learners must read the part of the textbook carefully, then confirm concept of each class's keywords before the class (1.5 hours), and take exercises written in the end of the section after the class (1.5 hours).
The classes will proceeded according the text books.
If there are few students, they will take turns reading and explaining the books.
