What is fuzzy logic?

I'm working with a couple of AI algorithms at school and I find people use the words Fuzzy Logic to explain any situation that they can solve with a couple of cases. When I go back to the books I just read about how instead of a state going from On to Off it's a diagonal line and something can be in both states but in different "levels"....

Defuzzification process of fuzzy sets in RDBMS

I have a table that stores all values..eg x1, x2, x3 which determines fuzzy sets. Degree of membership is assigned to each using mathematical functions for Low, Med, High. My rule 1 states that if x1 is high AND x2 is medium then probability of output is z. I then take min{x1,x2} to evaluate the rule. Rule 2 states that if x2 is high...

Fuzzy logic membership function in C

Hi, I'm trying to implement a fuzzy logic membership function in C for a hobby robotics project but I'm not quite sure how to start. I have inputs about objects near a point, such as distance or which directions are clear/obstructed, and I want to map how strongly these inputs belong to sets like very near, near, far, very far. Does ...

FuzzyDL doesn't work

hi to everyone, i am using FuzzyDL with Mac OS. the exit status is always 133 - no computation of the input (example files!). what is wrong ? ...

Comparing (similar) images with Python/PIL

I'm trying to calculate the similarity (read: Levenshtein distance) of two images, using Python 2.6 and PIL. I plan to us e the python-levenshtein library for fast comparison. Main question: What is a good strategy for comparing images? My idea is something like: Convert to RGB (transparent -> white) (or maybe convert to monochrome?...

What free expert system can You recommend (with higher functionality then CLIPS)?

Hi, I'm trying to find best free expert system, with the highest functionality. I know about CLIPS, but is there another system, for example being able to accept percent of confidence for each rule (fuzzy logic). I need it to know will I be able to do fast a short project using expert system, with highest functionality. But anyways, ...

Fuzzy logic in java

I have been given a new project module which involves fuzzy logic.It is to determine different Hydrometeors using fuzzy logic method.I have very little idea about what fuzzy logic is.So i would like to have some advice from people who have already done projects using fuzzy logic in java(like what are the basic programming strategies I ca...

How can I map a list of ranges to a single value?

I've only recently jumped into the world of iphone development and objective-c, so I'm still a bit lost as to how I might implement something like this. I have a float, and I have a list of ranges that float can fall within and the corresponding value I should return, eg: 10.0 - 14.5 : 1.0 14.5 - 17.0 : 2.0 17.0 - 23.0 : 2.5 23.0 - 32....

Fuzzy Logic . How to get the complement

Hi, i came across the following fuzzy logic example about fuzzy logic. Representing Age Problem 2-1. Fuzzy sets can be used to represent fuzzy concepts. Let U be a reasonable age interval of human beings. U = {0, 1, 2, 3, ... , 100} Solution 2-1. This interval can be interpreted with fuzzy sets by setting the universal space for age ...
