Learning objectives: 

  To
understand advanced classification and recognition techniques and to
learn how to apply the
algorithms and methods to problems in speech recognition,
computer graphics and natural language processing. To get acquainted with discriminative training and building hybrid
systems. 
Description: 

  Estimation of parameters Maximum Likelihood and ExpectationMaximization, formulation of the objective function of discriminative training, Maximum Mutual information (MMI) criterion, adaptation of GMM models, transforms of features for recognition, modeling of feature space using discriminative subspaces, factor analysis, kernel techniques, calibration and fusion of classifiers, applications in recognition of speech, video and text. 
Knowledge and skills required for the course: 

  Basic knowledge of statistics, probability theory, mathematical analysis and algebra.

Subject specific learning outcomes and competences: 

  The students will get acquainted with advanced classification and recognition
techniques and learn how to apply basic methods in the fields of speech
recognition, computer graphics and natural language processing.

Generic learning outcomes and competences: 

  The students will learn to solve general problems of classification and recognition.
