 B4B33RPZ Recognition and machine learning Extent of teaching: 2P+2C Guarantors: Matas J. Roles: PO,PZ,P Language ofteaching: CS Teachers: Drbohlav O., Matas J. Completion: Z,ZK Responsible Department: 13133 Credits: 6 Semester: Z

Anotation:

The basic formulations of the statistical decision problem are presented. The necessary knowledge about the (statistical) relationship between observations and classes of objects is acquired by learning on the raining set. The course covers both well-established and advanced classifier learning methods, as Perceptron, AdaBoost, Support Vector Machines, and Neural Nets.

Study targets:

To teach the student to formalize statistical decision making problems, to use machine learning techniques and to solve pattern recognition problems with the most popular classifiers (SVM, AdaBoost, neural net, nearest neighbour).

Course outlines:

 1 The pattern recognition problem. Overview of the Course. Basic notions. 2 The Bayesian decision-making problem, i.e. minimization of expected loss. 3 Non-bayesian decision problems. 4 Parameter estimation. The maximum likelihood method. 5 The nearest neighbour classifier. 6 Linear classifiers. Perceptron learning. 7 The Adaboost method. 8 Learning as a quadratic optimization problem. SVM classifiers. 9 Feed-forward neural nets. The backpropagation algorithm. 10 Decision trees. 11 Logistic regression. 12 The EM (Expectation Maximization) algorithm. 13 Sequential decision-making (Wald´s sequential test). 14 Recap.

Exercises outline:

Students solve four or five pattern recognition problems, for instance a simplified version of OCR (optical character recognition), face detection or spam detection using either classical methods or trained classifiers.
