NEURO-FUZZY SYSTEM FOR PROSTATE CANCER DIAGNOSIS

Attention! This page is for medical doctor only!

Fuzzy logic is the science of reasoning, thinking and inference that recognizes and uses the real world phenomenon that everything is a matter of degree. In the simplest terms, fuzzy logic theory is an estesion of binary theory that does not crisp definitions and distinctions. Instead of assuming everything must be defined crisply into black and white, that is, varying shades of gray (binary view) fuzzy logic is a methodology that captures and uses the concept of fuzziness in a computationally effective manner. This concept was developed 40 years ago by Lotfti Zadeh.

Neuro-fuzzy systems harness the power of the two paradigms: fuzzy logic and atificial neural networks.

I developed a neuro-fuzzy system based on data from 1030 men. Predictive variables were tPSA, %freePSA and age,

You can freely download the tools for this neuro-fuzzy system.

Remember that this tool can help the diagnosis but doesn't substitute the urological examination that is always irreplaceable!

Tool for excel: http://www.urologiaparma.com/excelfuzzyprostate.zip or http://www.urologiaparma.com/excelfuzzyprostate.exe (download the zip file and unzip the files in the directory C:\fuzzyprostate\excel )

Tool for access: http://www.urologiaparma.com/accessfuzzyprostate.zip or http://www.urologiaparma.com/accessfuzzyprostate.exe (download the zip file and unzip the files in the directory C:\fuzzyprostate\access ).

Tool for ASP file (you need to setup Internet Informetion Service IIS and typ http://localhost/fuzzyprostate/ASPShell.asp In internet explorer)

http://www.urologiaparma.com/aspfuzzyprostate.zip or http://www.urologiaparma.com/aspfuzzyprostate.exe (download the zip file and unzip the files in the directory C:\fuzzyprostate\asp ).

Those tools require in your computer a specific neural network program (neurosolution). You can download the complete program or the free demo of neurosolution at http://www.neurosolutions.com
