Keras

• is a high-level, deep-learning API developed by Google for implementing neural networks
• it can run on top of CNTK, TensorFlow, and Theano
• was adopted and integrated into TensorFlow in mid-2017. Users can access it via the tf.keras module. However, the Keras library can still operate separately and independently
