Course detail

Fuzzy Systems and Neural Networks

FSI-RNFAcad. year: 2020/2021

The course provides students with the introduction to the most commonly used paradigms of neural networks. Further, it shows technically oriented applications of neural networks and their practical use. The theory part is focused on neural dynamics - mainly it's activation, signals and activation models, synapse dynamics - both supervised and unsupervised learning (competitive learning, back-propagation); network architectures. Furthermore, the neural and fuzzy representation of structured knowledge is compared and used for controllers design.

Learning outcomes of the course unit

Knowledge of neural network functioning and their adequate use for data processing, specially for “intelligent“ controllers design.


The knowledge of matrix calculus is expected. The orientation in optimization methods and modelling is suggested.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

Course-unit credit requirements: active participation in seminars and individual elaboration of an assigned project. The examination comprises written and oral parts. The written part is represented by a test with four questions . Oral part consists of discussion on the written part with possible complementary questions. The evaluation is fully in the competence of a tutor according to the valid directives of BUT.

The course objective is for students to master basics of neural modelling and common use of neural models for data processing as well as the frame of “intelligent“ controllers design.

Specification of controlled education, way of implementation and compensation for absences

The attendance at lectures is recommended while at seminars it is obligatory. Education runs according to week schedules. The form of compensation of missed seminars is fully in the competence of a tutor.
