Recognition and machine learning
- The course cannot be taken simultaneously with:
- Pattern Recognition and Machine Learning (BE5B33RPZ)
- Department of Cybernetics
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.
Knowledge of linear algebra, mathematical analysis and probability and statistics.
