FUZZY COGNITIVE MAP EXAMPLE Josef Betancourt,
CIS 71351,356
September 25, 1993
FCM.CPP is a simple implementation of the Fuzzy Cognitive Map
example found in the texts:
1. Neural Networks and Fuzzy Systems. Kosko, B. Pg. 154.
2. Fuzzy Thinking. Kosko, B. Pg. 222.
3. Fuzzy Logic. McNeill D., Freiberger, P. Pg. 237.
This version is a little more general purpose than a previous
upload. Command line parameters are used to allow this. The
syntax is:
fcm <FCM file><policy file><matrix size><cell><value><thresh>
The FCM is in file AFRICA.TXT.
Investment policy vector is in INVEST.TXT.
Disinvestment is in DIVEST.TXT
To run the investment policy example:
fcm africa.txt invest.txt 9 1 1 .5
To run the disinvestment policy:
fcm africa.txt divest.txt 9 1 0 .5
-------------------------------------------------------------
I used a very nice matrix class called BUMP,
Beginner's Understandable Matrix Package. It is found in the
Borland C++ forum on CIS (Go BCPPDOS); the file is BUMP.ZIP. The
author is: Clopper Almon, Compuserve: 73377,1466
-------------------------------------------------------------
USE:
To create the executable compile and link FCM.CPP with
BUMP.CPP, using Large memory model. I would appreciate any
feedback such as (gentle) criticism and improvements.
-------------------------------------------------------------
COMMENTS:
Of course, a general purpose interactive graphical system
where the FCM can be entered graphically by multiple experts and
the inference process is visually presented would be nice. It
should be a FCM CAD system!
What are FCMs good for? As presented in the texts so far,
they seem to be an alternative to traditional Expert Systems.
One of the big advantages is that FCMs can be combined to better
capture the knowledge of multiple experts. Whereas trees are
hard to combine and reason with.
I believe the only place using FCMs is Japan.
