A fuzzy system for python with fuzzy reasoning and classification.

Project description

Fuzzy system

Just a other python fuzzy rule-based system and reasoning package. Based on the lecture's given by Ning Xiong at Märlardalens University. Writen and implmented by @byteofsoren.

Installation.

pip install fuzzy_system

Basic usage

Assume that intended system for opening a valve dependent on price of electricity and the temperature in the environment.

Assume that the fuzzy set for the temperature and cost looks like this: Temperature Electricity cost This is implemented like this in this module:

>>> import python_fuzzy_system as fuzzy

>>> cold = fuzzy.fuzzy_member_pointlist([[-5,1],[5,0]])
>>> warm = fuzzy.fuzzy_member_pointlist([[0,0],[5,1],[10,1],[15,0]])
>>> hot = fuzzy.fuzzy_member_pointlist([[5,0],[15,1]])

>>> cheap = fuzzy.fuzzy_member_pointlist([[8,1],[12,0]])
>>> good = fuzzy.fuzzy_member_pointlist([[8,0],[12,1],[16,0]])
>>> expensive = fuzzy.fuzzy_member_pointlist([[12,0],[16,1]])

Now fire each individual member can be done like:

>>> cold.fire(1.5)
0.35

Creating rules for the system

Lets define a set of rules called Rn. |Rule| Condition | Do | |---|---|---| | R1 | If Cheap AND Cold | Then Open | | R2 | If Hot AND (Cheep OR good) | Then HalfOpen | | R3 | If Expensive AND Hot | Then Closed

r1 = cheep*cold
r2 = hot*(cheep + good)
r3 = expensive*hot
