The TensorFlow Core API is a set of modules written in Python. It is a system where computations are represented as graphs. The R tensorflow package provides complete access to the TensorFlow API from R. TensorFlow represents computations as a data flow graph, where each node represents a mathematical operation, and directed arcs represent a multidimensional data array or tensor that operations are performed on. In this recipe, we'll build and train a model using the R interface for the TensorFlow Core API.
