Anfis-package: Adaptive Neuro Fuzzy Inference System in R

Description Author(s) References


The package implements ANFIS Type 3 Takagi and Sugeno's fuzzy if-then rule network. This package includes the new following features:

  1. 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.

  2. Type 3 Takagi and Sugeno's fuzzy if-then rule

  3. Full Rule combinations, e.g. 2 inputs 2 membership functions this means that 4 fuzzy rules will be created.

  4. Different learning strategies:


    Hybrid learning, i.e. Descent Gradient for precedents and Least Squares Estimation for consequents.


    on-line version with hybrid learning.


    Adaptive learning coefficient and momentum term.

  5. Multiple outputs support, i.e., the same input partition can be used to predict more than one output variable.
