Example won't work #3

Closed Raphango closed 6 years ago

Raphango commented 6 years ago

Hi!

Thanks for your work, but I'm afraid your example isn't working. The error just keeps going up and up, even raising the epochs number. There is no going down...

figure_1 figure_2

Is there any way to fix this?

Thanks in advance!

Thanks Angelo. I'm afraid I'm not sure why you are seeing those results. I haven't looked at this code for several years, but it was definitely working when the package was first created and should work with Python 2.

My only suggestion is to debug as the mechanics of ANFIS have not changed!

I've tried running in Python 2.7 as well, but with the same results.

Do you have any other example code?

Thanks again for the prompt answer!

@twmeggs,

I got the same results mentioned by @Raphango. Please, run again the example and show us your results. Thanks!

gcunhase commented 6 years ago

I have the same issue

twmeggs commented 6 years ago

@Raphango @erralves @gcunhase Thanks for your patience. I've altered the initial state values for some of the parameters of the membership functions in the tests.py and the results converge now. In general, altering the initial parameters values has a large effect on how the algorithm then performs.
