Getting Started with Deep Learning: A Review of Available Tools
This list is woefully incomplete. It should be titled "A Review of Some Tools". Those it doesn't include, or does not give proper mention to in its top table, are: Chainer, DyNet, Paddle and Deeplearning4j.[0]Even Keras, the third most popular DL library, is given short shrift, even though it is easier to use than TensorFlow, and can handle Theano, TF, CNTK and Deeplearning4j as backends.All of the missing libs have significant advantages over TensorFlow, which appears to be winning chiefly on Github stars. Notably speed and integrations.[0]
