The Keras extension allows to leverage Keras directly from RapidMiner. Keras is a high-level neural network API, supporting popular deep learning libraries like Tensorflow, Microsoft Cognitive Toolkit (CNTK), and Theano as computation backends. In the new Keras extension for RapidMiner Studio, we provide a set of operators that allow an easy visual configuration of Deep Learning network structures and layers. Calculations are pushed into the Python-based backend libraries. If those are configured correspondingly, you can transparently leverage the computing power of GPUs.
