## Course Description[edit]

Pattern recognition techniques are used to automatically classify physical objects (handwritten characters, tissue samples, faces) or abstract multidimensional patterns (n points in d dimensions) into known or possibly unknown number of categories. The design of a pattern recognition system consists of the following main modules: (i) sensing, (ii) feature extraction, (iii) decision making, and (iv) performance evaluation. The availability of low cost and high-resolution sensors (e.g., digital cameras, microphones and scanners) and data sharing over the Internet have resulted in huge repositories of digitized documents (text, speech, image and video). The need for efficient archiving and retrieval of this data has fostered the development of pattern recognition algorithms in new application domains (e.g., text, image and video retrieval, bioinformatics, and face recognition).

A pattern recognition system can be designed based on a number of different approaches: (i) template matching, (ii) geometric (statistical) methods, (iii) structural (syntactic) methods, and (iv) neural (deep) networks. This course will present an introduction to statistical pattern classification. The fundamental background for the course is probability theory. The course will cover techniques for visualizing and analyzing multi-dimensional data along with algorithms for projection, dimensionality reduction, clustering, and classification. The course will present various approaches to classifier design so students can make judicious choices when confronted with real pattern recognition problems. The course is suitable for students in engineering, mathematics, and computer science, who have a basic background in calculus, linear algebra, and probability theory (as typically covered in an undergraduate program in any one of these fields), and who have some interest in exploring the field of pattern recognition.
