Kerasis an Open Source Neural Network library written in Python that runs on top of Theano or Tensorflow. It is designed to be modular, fast and easy to use. It was developed by François Chollet, a Google engineer. Keras doesn’t handle low-level computation. Instead, it uses another l...

FakeApp relies on neural networks, which are notoriously expensive to train. Despite their cost, the process of training a neural network is highly parallelisable. For this reason, most Machine Learning frameworks (such asKerasandTernsorFlow) can dispatch the computation on aGPU. GPU stands for...
