**Keras** is an API used for running high-level neural networks. The model runs on top of TensorFlow, and was developed by Google.

In this particular example, a neural network will be built in Keras to solve a regression problem, i.e. one where our dependent variable (y) is in interval format and we are trying to predict the quantity of y with as much accuracy as possible.

Previously, I demonstrated how such a neural network can be devised with Python. However, it just so happens that Keras also has an R interface as well, and therefore it is possible to conduct this analysis through R.
