I am trying to use Mathematica Neural Network package to solve some
classification problem but running out of memory during this call:
NeuralFit[net, in, out]
The amount of training data I have is moderate (10389 rows, 120 inputs
and 6 outputs):
In[16]:= Dimensions[in]
Out[16]= {10389, 120}
In[18]:= Dimensions[out]
Out[18]= {10389, 6}
The network have 2 layers with 15 and 5 neurons:
net = InitializeFeedForwardNet[in, out, {15, 5}, OutputNonlinearity ->
Sigmoid]
I am repeatedly getting "No more memory available" (and suggestion to
use 64 bit version on Mac, pointing to a broken link, which does not
apply anyway since I have a Home Edition).
I tried to contact support, but they are taking too long to resolve
this, so I wondering is somebody else have seen similar problem.
I am do not see why it should need too much memory for this kind of
network. I suspect maybe there is a bug in training algorithm
implementation?
Sincerely,
Vadim
