A very basic timing comparison on the performance of a setup of Theano using the MNIST dataset with multiple layer perceptron. A gain in performance of almost 18% is achieved with GPU, and significant improvement is observed using T-test.
Theano needs no introduction in the field of deep learning. It is based on Python and supports CUDA. Keras is a libray that wraps the complexity of Theano to provide a high level abstraction for developing deep learning solutions. 149 more words
