You can specify either of these values, or another Python package entirely as the implementation. Keras 3d Deconvolution. Objects exported from other packages. Here we go over the sequential model, the basic building block of doing anything that's related to Deep Learning in Keras. Rather than picking one single tensor library and making the implementation of Keras tied to that library, Keras handles the problem in a modular way, and several different backend engines can be plugged seamlessly into Keras. Use the keyword argument input_shape (tuple of integers, does not include the samples axis) when using this layer as the first layer in a model. The Keras R interface uses the TensorFlow backend engine by default. A few months ago I demonstrated how to install the Keras deep learning library with a Theano backend.
