Teachers

Included in study programs

Teaching results

In particular, students acquire the following abilities:
A. understanding the semantic uncertainty of real-world and appropriately handling by fuzzy sets and fuzzy logic,
B. creating flexible database queries,
C. logically aggregating elementary conditions,
D. developing and interpreting linguistic summaries from data,
E. applying fuzzy inference and classification models,
F. handling and managing work with imprecise data in databases,
G. applying acquired knowledge and skills in solving real-world tasks,
H. gaining the overview of the role of fuzzy logic in explainable artificial intelligence.

Indicative content

1. Introduction into fuzzy sets and fuzzy logic, and comparison with the classical logic and set theory.
2. Fuzzy arithmetic.
3. Logic aggregation functions and their applications in evaluating entities and summarizing information from data.
4. Flexible (fuzzy) relational database queries.
5. Empty and overabundant problems in queries.
6. Linguistic summaries on numeric and categorical data.
7. Fuzzy inference (Mamdani and Sugeno model, defuzzification).

Requirements to complete the course

Exam 60% The exam consists of two parts: the evaluation of the theoretical knowledge and knowledge of modelling specific tasks. The first part, verifies the achievement level of the teaching results A., D., F., H., whereas the second part verifies the level of the teaching results B., C., E., G.
Assignments during the semester 40% The purpose of seminars is to develop and defend the tasks related to modeling uncertainties and a test. The evaluation of the students also their activity during the semester. The following teaching results are evaluated B., C., D., E. G.
