In alecuba16/HDGSOM: High Dimensionality Growing Self-Organizing Maps

hdgsom

Implementation of High Dimensional Growing Self Organizing Maps in R

Improves the GSOM by:

• New initialization method

• modify the GT calculation from:

  

  to:

  

The original paper claims that this modification improves the model with high dimensionality data.

TODO

• Implement the calibration phase described in the paper.
• openMP Parallelization C code.

Installation

With R devtools

install('devtools')
library('devtools')
install_github('alecuba16/HDGSOM')

Building manually:

Make a R Package out of the folder gsom_pkg using the command:

    R CMD build hdgsom-pkg

Windows may need a binary Package which can be obtained by:

    mkdir temp_location
    R CMD INSTALL --build -l temp_location HDGSOM_0.1.2.tar.gz

installation Linux (in R):

    install.packages(repos=NULL,"HDGSOM_0.1.2.tar.gz")

installation Windows (in R):

    install.packages(repos=NULL, "HDGSOM_0.1.2.tar.gz", type="binary")
