%description
Various algorithms related to linguistic fuzzy logic: mining for
linguistic fuzzy association rules, composition of fuzzy relations,
performing perception-based logical deduction (PbLD), and forecasting
time-series using fuzzy rule-based ensemble (FRBE). The package also
contains basic fuzzy-related algebraic functions capable of handling
missing values in different styles (Bochvar, Sobocinski, Kleene etc.),
computation of Sugeno integrals and fuzzy transform.
