History of Keras

Keras was developed by Google engineer named François Chollet. It was developed as part of research project called ONEIROS (Open-ended Neuro-Electronic Intelligent Robot Operating System) and it was released in March 2015. The goal of Keras was to enable fast experimentation with deep neural networks. Later, Keras was incorporated into TensorFlow as ‘tf.keras’, which made it an official high-level API of TensorFlow while still supporting its standalone version that could interface with other computational backends like Theano or CNTK....
