Type2Fuzzy Project
A type-2 fuzzy logic library providing:
- Ways to define and work with general type-2 fuzzy sets
- Ways to define and work with interval type-2 fuzzy sets
- Ways to generate z-sliced sets from general type-2 fuzzy sets
- Functions to perform wavy-slice type-reduction (Mendel-John) on general type-2 fuzzy sets
- Functions to perform interval type-2 reduction (Karnik-Mendel)
- Functions to perform partial-centroid type-reduction on general type-2 fuzzy sets
- Functions to perform defuzzification of type-1 fuzzy sets
- Tools to measure the performance of algorithms
- Tools to plot general, interval and z-sliced type-2 fuzzy sets and type-1 fuzzy sets and more
- Ways to define and work with type-1 fuzzy sets
- Ways to define and work with type-1 linguistic variables
and more
All type2fuzzy wheels distributed on PyPI are BSD licensed.
Examples of how this library was used to work some famous type-2 fuzzy logic papers can be found here.
