title: Neural Network training in parallel, better to use Hadoop or a gpu?
body: <p>I need to train a neural network with 2-4 hidden layers, not sure yet on the structure of the actual net. I was thinking to train it using Hadoop map reduce (cluster of 12 pcs) or a gpu in order to get faster results. What do you think it would be better ? Also are there any available libraries that have these already implemented?
  Thanks</p>
