Building deep neural networks just got easier. TensorFlow has announced that they are incorporating the popular deep learning API, Keras, as part of the core code that ships with TensorFlow 1.2. In the words of Keras' author François Chollet, "Theano and TensorFlow are closer to NumPy, while Keras is closer to scikit-learn," which is to say that Keras is at a higher level compared to pure TensorFlow and makes building deep learning models much more manageable. TensorFlow is one of the fastest, most flexible, and most scalable machine-learning libraries available. It was developed internally by Google Brain and released as an open-source library in November 2015.
