Anfis-package: Adaptive Neuro Fuzzy Inference System in R
Description
The package implements ANFIS Type 3 Takagi and Sugeno's fuzzy if-then rule
network. This package includes the new following features:
- Membership Functions (MF) flexible framework:
- Flexible user-defined membership functions(MF) extensible class.
- Independent number of (MF) for each input.
- Different MF types, if required, for each input.
- Type 3 Takagi and Sugeno's fuzzy if-then rule
- Full Rule combinations, e.g. 2 inputs 2 membership functions this
means that 4 fuzzy rules will be created.
- Different learning strategies:
- trainHybridJangOffLine
- Hybrid learning, i.e. Descent Gradient
for precedents and Least Squares Estimation for consequents.
- trainHybridJangOnLine
- on-line version with hybrid learning.
- trainHybridOffLine
- Adaptive learning coefficient and momentum
term.
- Multiple outputs support, i.e., the same input partition can be used
to predict more than one output variable.
