hello Juan on fuzzylite aid for students‏

[Unknown]

Greetings Juan Rada, I am developing an expert system for diagnosis of pests and diseases on rice. This is based on graduation thesis, I would like to know how JFuzzyLite, gives a result for example the size of a male insect is 2.50 to 3.10mm and a female of 2.90 to 3.80 but what distinguishes the two is the color, such rules would

IF INSECT IS BROWN AND SIZE> = 2.50 AND SIZE <= 3.10 IS THEN INSECT CIGARRITA_MACHO
ELSE IF COLOR IS BLACK AND SIZE>=2.90 AND SIZE<=3.80 THEN INSECT CIGARRITA_HEMBRA

The question is whether JFUZZYLITE GIVE ME COULD RESULT “CIGARRITA_MACHO” or the result given in numbers, could explain or would have an example. Thank you very much in advance.

Hi Roberth,

fuzzylite deals with uncertainty. The type of rules would be more like:

if colour is light and size is small then insect is cigarrita_macho
if colour is dark and size is big then insect is cigarrita_hembra

The output will be a degree of “confidence” with which the insect is cigarrita_hembra and _macho, e.g., 0.8/hembra +0.2/macho. You could also defuzzify this output and obtain a decimal value in the range of defition of insect. For example, if insect is defined in [0.0,1.0], the defuzzification could be 0.8333.

Please, revise the examples in QtFuzzyLite.

I hope this helps.

Cheers,
