How to do it...

1. This chapter will cover the MXNet and TensorFlow packages (developed in C++ and CUDA for a highly optimized performance in GPU).
2. Additionally, the h2o package will be used to develop some deep learning models. The h2o package in R is implemented as a REST API, which connects to the H2O server (it runs as Java Virtual Machines (JVM)). We will provide quick setup instructions for these packages in the following sections
