Hi,

 

I am a new user in Gnu Octave. I started working on the Neural Network package (nnet 0.1.13).

I tried the example 1 (MLP9_1_1.m) in the installation folder but didn’t work, the error message is :

 

error: 'df_mapper' undefined near line 22 column 10

error: called from

    finite at line 22 column 8

    train at line 125 column 11

    MLP9_1_1 at line 91 column 7

 

I use Octave 5.1.0.0 on Windows 7.

Could anyone help me?

Thanks!

Dear Francesca,

Did not load the package?

>> pkg load nnet

But keep in mind that the nnet-0.1.13 package for Octave Forge is hopelessly outdated [1] from 2010-12-03.

In 2017 we had a GSoC Project by Enrico Bertino [2] about a new implementation of the nnet package.

Maybe you can make more out of it [3].

Best,

Kai
