Artificial Neural Networks recommendation

Hi,

I'd like to use ANNs in python, especially Simple Recurrent Networks.

Ideally I'd like to find a quick, pythonic module that is able to
simulate different styles of network architectures including some types
of recurrent networks (must: SRN/Elman, may: other recurrent networks
like ESN or LSTM to experiment with them).

So far I found the following Python ANN modules:
- - PyNN (just a builder, requires external simulator) –
http://neuralensemble.org/trac/PyNN/
- - Con-x (part of pyro) – http://pyrorobotics.org/?page=Conx
- - PyNeurGen (includes genetic algorithms) –
http://pyneurgen.sourceforge.net/
- - ffnet (only fast forward) – http://ffnet.sourceforge.net/
- - brian (spiking networks) – http://www.briansimulator.org/
- - PyBrain (machine learning) – http://pybrain.org/

Can you give me a recommendation or a review on some of these? Are there
other modules for simulating ANNs?

Greetings,
Gereon

PyNN and Brian are intended more for biologically-realistic neural
networks (for some value of realistic), aka neuronal networks, so I
guess you can rule them out (similar tools that you might come across
are NEST, NEURON, PCSIM).

Cheers,

Andrew

Hi,

Thanks for the answers:
Fann <http://leenissen.dk/fann/> has python bindings.
I saw it, but forgot to include it in my listing.

networks (for some value of realistic), aka neuronal networks, so I
guess you can rule them out (similar tools that you might come across
are NEST, NEURON, PCSIM).
Yes, I thought so. (I might keep them in mind anyway, if I get to a more
biologically approach someday, just like ffnet, which doesn't support
recurrent networks but might be good in what it does.)

Fann seems to be inable to simulate recurrent networks, too. (There are
some older discussions, but I found no trace of a successful
implementation.)

So my main interest would be Con-x, PyNeurGen and PyBrain. Can you tell
me anything about these modules or point me to where to find more
information?

Greetings,
Gereon
