Method Details

[hide private]

init(self, description=`''`, variables=None, rules=None)
(Constructor)

source code

Constructor.

Parameters:

description (string) - description

Overrides: object.__init__

fuzzify(self, input)

source code

Fuzzify the inputs. The input dictionary contains the input values for the named variables.

defuzzify(self, output)

source code

Defuzzyfy the variables. The output dictionary serves as container and provides the names of the variables to read.

calculate(self, input, output)

source code

Do a complete fuzzy calculation step. The input dictionary contains the input values for the named variables. The output dictionary serves as container and provides the names of the variables to read.

repr(self)
(Representation operator)

source code

Return representation of instance.

Returns: string: representation of instance
Overrides: object.__repr__
