Subject specific learning outcomes and competences
The students will get acquainted with the problem of machine learning applied to pattern classification and recognition. They will learn how to apply basic methods in the fields of speech processing and computer graphics. They will understand the common aspects and differences of the particular methods and will be able to take advantage of the existing classifiers in real-situations.
The students will get acquainted with python libraries focused on math, linear algebra and machine learning. They will also improve their math skills (probability theory, statistics, linear algebra) a programming skills. The students will learn to work in a team.
To understand the foundations of machine learning with the focus on pattern classification and recognition. To learn how to apply basic algorithms and methods from this field to problems in speech and image recognition. To conceive basic principles of different generative an discriminative models for statistical pattern recognition. To get acquainted with the evaluation procedures.
Why is the course taught
Recent years witnessed a boom of machine learning or pattern recognition applications. More and more devices can be controlled using voice or gestures. Digital cameras automatically detect faces in the captured images in order to automatically focus or somehow react on it. Virtual agents in mobile devices can recognize speech and search for relevant answers to our queries. The quality of the current systems for automatic recognition of a person's identity from voice recording or from face photo already significantly exceed the human abilities.
In this class, the students should learn how these technologies work. They will learn about the basic algorithms and models, which, using some training examples, automatically learn to recognize nontrivial patterns in audio recordings, images or other signals or input data.
