Installation

Dependencies

Ruta is based in the well known open source deep learning library Keras and its R interface. It has been developed to work with the TensorFlow backend. In order to install these dependencies you will need the Python interpreter as well, and you can install them via the Python package manager pip or possibly your distro’s package manager if you are running Linux.

Otherwise, you can follow the official installation guides:

Ruta package

All R dependencies will be automatically installed. These include the Keras R interface and purrr. For convenience we also recommend installing and loading either magrittr or purrr, so that the pipe operator %>% is available.

Usage

The easiest way to start working with Ruta is to use the autoencode() function. It allows for selecting a type of autoencoder and transforming the feature space of a data set onto another one with some desirable properties depending on the chosen type.

You can learn more about different variants of autoencoders by reading A practical tutorial on autoencoders for nonlinear feature fusion.

Ruta provides the functionality to build diverse neural architectures (see autoencoder()), train them as autoencoders (see train()) and perform different tasks with the resulting models (see reconstruct()), including evaluation (see evaluate_mean_squared_error()). The following is a basic example of a natural pipeline with an autoencoder:
