III. Course objectives
The lecture presents the notions related to adaptive data processing, methods that are based on basic probability and modern machine learning algorithms. We present methods to classify data, to perform regression or clustering on various data types.	

IV. Course contents
Stochastic data modelling is the application to various types of data of algorithms that exploit the rules of probability and allow direct representation of the stochastic nature of the real world. In order to extract information, usually one has to include prior knowledge into the algorithm. The inclusion of the prior knowledge is possible via the rules of probability. Prior knowledge is the model we want to use. If there are huge data-sets available, then one must use statistical methods, for a few data a lot more emphasis is to be put on the model. The algorithms depend also on the type of the problem we want to solve. The course is aimed as a practical introduction to various models from machine learning and to familiarise the students with the use of randomness and stochastic models.
