Re: [Discuss-gnuradio] [SOCIS] Keras, TensorFlow and GNU Radio Blocks

Hey,

I think it should be possible to do it only with the Keras API. Then
it's fully portable, but the GPU stuff for Tensorflows is getting tricky
(or I haven't found an easy solution yet).

Keras has all the pooling and convolution sutff that you need, so
probably give it a try. Theano has really some advantages!

Greetings,
Stefan
