File Information
Description

This library is for those who want to use the ANFIS/CANFIS system in the Simulink environment. Each model is implemented for training and operation in a sample-by-sample, on-line mode. For details see the included release notes. The main reference used to develop all the ANFIS/CANFIS models is:
Neuro-Fuzzy and Soft Computing: A Computational Approach to Learning and Machine Intelligence, Jyh-Shing Roger Jang, Chuen-Tsai Sun, Eiji Mizutani. Prentice Hall, Sept. 1997.

@ Alex Mao: I'm afraid that you can't increase/decrease the samples of this demo. If you want to alter the number of samples, you must modify the file SimDataGenAnfis1.m which is employed in order to create and formulate the training and checking data as required by simulink. Also, you can't alter the training/checking data sizes via the LE step function.

Hi llias,

Thanks for your effort, I have tried the ANFIS_Scatter_MG based on your manual and it worked well. However, as your test data has 1000 samples, when I increase samples, the ANFIS scatter still output the first 1000 sample, can you provide some comments for solving this problem, thanks in advance.

@Richard: Please describe the problem in more detail.

I am having issues understanding the states array that the anfis_art block prints out for the purposes of reconstructing the membership functions after each time step.

@ In-hwan. Yes, they are the same. You must compile combinem.c with mex and then call this function with same arguments as with comb that appears in grad_check_anfis_grid.m. Good Luck.

Thank you for your prompt response. ^^

But i can't find the "comb.c" file in your zip files.
Do you mean that "combinem.c" file is same with the "comb.c" file???

or I should find "comb.c" file for myself???

21 Nov 2014 Ilias Konsoulas

@ In-hwan. This message appears because you haven't compiled the comb.c file to an mex executable using the mex command. Apply the mex command to the given comb.c source file and then you are ready to proceed with your simulations. Function comb.c was implemented in C for faster execution. Good Luck.

When i run the file "grad_check_anfis.m"
an error happens on the function "comb()"

the error message is:
=============================
Undefined function 'comb' for input arguments of type 'double'.

Error in grad_check_anfis_grid (line 116)
precond = comb(Out1);
=============================
How can i find a file defining the function "comb()"??

@ Junho.

When you run a demo for the very first time you must comment the line "load anfis_scatter_states.mat" or similar. In the "Initial States" entry you must enter a zero indicating you start training from scratch. When the first simulation session is complete, the anfis_scatter_states.mat has been generated in the current directory. Then you must uncomment the line "load anfis_scatter_states.mat". When you bouble click the box the learned states are loaded on the workspace. Then, in the "Initial States" entry of the form, you must enter the name of the variable (matrix) that contains the learned states.

Dear Ilias,

I was following your manual to test your ANFIS demo version to see how ANFIS works. I'm pretty sure I fellow your direction correctly but it still makes me little confused of getting ~~.mat file. First, right click and go to properties of "Double-Click to load MG Data and ANFIS States" and open "OpenFcn*" inside Callbacks tab. Then comment % "load anfis_scatter.mat" and double-click the MG data box itself. After this part, I run this program to get "anfis_scatter.mat" but it never works for me. It keeps giving me an error "anfis_scatter_states is undefined". From your guide, I have to enter the name of variable under "Initial ANFIS States" but I really have no idea which variable I have to put in to get ~~.mat file. If you don't mind, Could you give me an advise of your program?

Dear Ilias,
Thank you for the toolbox. However, I am getting the following error:
Error in S-function 'ANFIS_Grid_MG/ANFIS (Grid)/ANFIS': S-Function 'anfisim_grid' does not exist
This happens with any of the other blocks as well. Any help is much appreciated.

@Mohamed: Ok, thanks for the feedback. The bug was fixed. You may run every model with a single input signal form now on.

can we use the anfis scatter with only one input because an error appears

Roby, this is a problem caused by a malfunctioning (or non-existent) Signal Procesing Blockset. For more info, have a look here: http://www.mathworks.com/matlabcentral/newsreader/view_thread/103155 . Good Luck.

Thank you sir
I do what ever you tell me but there is also another error is come

Failed to load library 'dspstat3' referenced by 'CANFIS_ART_Lorenz/RMS'

Caused by:
Unable to load block diagram 'dspstat3'

Roby, right-click on the block named "Double-click to load Lorenz Attractor Data". Select Block Properties -> Callbacks -> OpenFcn. There, together with other commands, add the following definition: sim_time = 2000; Also, note that in Simulation/Configuration Parameters/Stop Time enter: sim_time. And you're done.

i have a problem with CANFIS_ART_Lorenz.mdl

Error evaluating expression 'sim_time' for 'Stop time' specified in the Configuration Parameters dialog for block diagram 'CANFIS_ART_Lorenz': Undefined function or variable 'sim_time'.

so kindly please help me

Nice work.
Thank you.

Please note that the recently added feature of "gradient consistency checking" is introduced in par. 7.2 of the latest version of the NFA library user's manual.

Dear Mr. Ilias Konsoulas

i have a problem with CANFIS_SCATTER
as when i enter two inputs with two error signals to get 2 outputs using MUX block it gives me an error during running by "Index exceeds matrix dimensions."

To Sally and others: In the updated version of the NFA User's Manual, a new section has been added describing how to run successfully the demos on your computer. Good Luck and thanks for your patience.

02 Oct 2012 Ilias Konsoulas

Ok, in the next few days I'll add a new section on the user's guide: "NFA User's Manual v2.pdf"
to describe in more detail how to run successfully the demos. Just wait a little bit. Thanks.

Dear Ilias Konsoulas,

Thanks for introducing the useful ANFIS library. I tried to run the demo programs but still gave me errors. Can you help me how to run that demos, Thank you so much.

Quick fix: rename library file NFA.mdl to NFA_matlab.mdl .

tying to run demo models gives erros as:

*Failed to load library 'NFA_matlab' referenced by 'ANFIS_Grid_MG/ANFIS (Grid)'
*Unable to load block diagram 'NFA_matlab'

How can i fix this? please help.

Thanks

Updates
10 Apr 2012 1.1

I have updated only the following form entries: a)Description, b)Tags c) Acknowledgement of other submissions.

23 Apr 2012 1.3

Minor code changes, better comments and NFA User Guide corrections.

09 Jul 2012 1.4

OK, I corrected the name of the library file from NFA.mdl to NFA_matlab.mdl in order to make demos runnable.

24 Oct 2012 1.26

In the latest version of the users guide, I have included a new section describing how to make the demos runnable on your computer and briefly outlining what each demo is about.

09 Jul 2013 1.27

Introduced the method of gradient consistency checking. This assures the correctness of your backprop implementation. I also provided .m scripts that perform gradient checking to all (C)ANFIS functions of this library.

06 Jun 2014 1.28

Fixed a bug in anfisim_scatter.m that prevented run with a single input. All models were tested for single input run successfully.

31 Mar 2015 1.29

Improved S-function syntax. Also killed a small bug. Updated library should run a bit faster.

01 May 2015 1.30

Killed some redundant variables and commands in s-function scripts. Added some new comments. Also introduced use of "if any(logical_condition)" loops instead of "if ~isempty(logical_condition) which should be a bit faster.
