Learning Outcomes

Pattern recognition is the scientific field that deals with the assignment of a label to a given input value. An example of pattern recognition is classification, which attempts to assign each input value to one of a given set of classes. The course aims to cover the most popular in the literature techniques for pattern recognition, as they are typically employed in a number of practical applications, such as speech and audio recognition, image and video analysis, biometrics and bioinformatics. The course covers the most commonly used classification algorithms, feature selection techniques, data transformation methods, and data clustering.

Students, upon successful completion of the course, will be able to:

A) Understand the key standards recognition methodologies

B) Analyze problems in various areas of application, such as voice and audio recognition, image and video analysis, biometrics and bioinformatics.

C) Choose the best classifiers, feature selection methods, data transformations, and clustering.

D) Evaluate standard pattern recognition systems
