NeuralFit running out of memory

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
