darch

Create deep architectures in the R programming language

Installation

The previous stable version of darch (0.12.0) can be installed from CRAN using

install.packages("darch")

When using devtools, the latest git version (identifiable by a version number ending in something greater than or equal to 9000 and by the fact that it is regularly broken) can be installed using

install_github("maddin79/darch")

or, if you want the latest stable version (0.13.0),

install_github("maddin79/darch@v0.13.0")

Then, use ?darch to view its documentation or example("darch") to view some simple examples. For further examples, see the examples directory.

Building

Assuming you use RStudio, open the darch.Rproj after cloning the repository. Make sure you have gcc-fortran installed (part of the r-base-dev package on ubuntu). Now install the dependencies:

install.packages(c("ggplot2", "reshape2", "futile.logger", "caret", "Rcpp", "RcppParallel"))

You can then build the package using Build -> Clean and Rebuild.

About

The darch package is built on the basis of the code from G. E. Hinton and R. R. Salakhutdinov (available under Matlab Code for deep belief nets : last visit: 12.11.2015).

This package is for generating neural networks with many layers (deep architectures) and train them with the method introduced by the publications "A fast learning algorithm for deep belief nets" (G. E. Hinton, S. Osindero, Y. W. Teh) and "Reducing the dimensionality of data with neural networks" (G. E. Hinton, R. R. Salakhutdinov). This method includes a pre training with the contrastive divergence method published by G.E Hinton (2002) and a fine tuning with common known training algorithms like backpropagation or conjugate gradient, as well as more recent techniques like dropout and maxout.
