Lecturer:

Tutor:

Supervisor:

Department of Circuit Theory

Synopsis:

Information about the basic principles and possibility of the application of the neural informative technology for the signal processing are the main topic. The lectures are devoted to the introduction into the artificial neural networks theory and applications, to the choice and the optimisation of the structures and the neural network applications at the speech recognition and synthesis are investigated in detail. Neural Network Toolbox of Matlab system is used in exercises.
