NEFCLASS - Neuro-Fuzzy Classification
NEFCLASS is short for NEuro-Fuzzy CLASSification and it is used for data analysis by neuro-fuzzy models. It
can learn fuzzy rules and fuzzy sets by supervised learning. NEFCLASS has the following features:
- It represents a fuzzy classification system
- It can learn fuzzy classification rules incrementally
- It learns fuzzy sets by using simple heuristics
- The learning algorithm does not afflict the semantics of the underlying fuzzy classifier. The system is always
interpretable in terms of fuzzy classification rules.
- NEFCLASS is available in two implementations

|NEFCLASS-J is the latest implementation of the NEFCLASS model in JAVA. It
was written in 1999 and there are currently no plans to continue to work on this implementation. The source code
is not available at the moment.
Please note: NEFCLASS-PC is no longer maintained. It was written for MS-DOS 16-bit computers
and it won't run without problems on modern Windows-XP 32-bit systems.
You can find some
useful information from Microsoft on how to run legacy software.
Check the section on "How to Run MS-DOS-based Games on Windows XP".
Some users reported that they experienced the "Runtime error 200 at 0003:25F5". Apparently, this is caused
by the CPU speed of modern PCs which is too fast for applications compiled by Turbo Pascal.
One user found that this can be resolved by using a program called SLOWDOWN, which resides in the memory of a command shell
and slows down the speed of CPU. Slowing down the CPU speed to 5Mhz of a 80486 computer level,
reportedly would let NEFCLASS-PC start up normally.
We have not tried this ourselves, so this comes without
any guarantee of working.
The Slowdown program has been written by Bret Johnson and can be downloaded at
NEFCLASS-PC is a software tool for MSDOS Personal Computers (80286, 2 MB and VGA needed). It was written by
Ulrike Nauck in Turbo Pascal and has a Turbo Vision interface (text windows). You can use
it to learn a fuzzy classifier from data, graphically display learning results, save fuzzy rules as text, and compute
some simple statistics on the training data.
Please note: NEFCLASS-X is no longer maintained.
NEFCLASS-X is an implementation for UNIX by Thomas Hoferichter. It is not the final version, and has not all
the features of the PC version. However, it already has a nice TCL interface, and comes including the source code
(C++). We are currently working on completing this version, so please check back from time to time!
