Installation

Clone this repository or download the source code.

Usage

Call decomposition = require "decomposition" and then any of the following:

  • decomposition.pca(x),

  • decomposition.lda(x, y),

  • decomposition.lpp(x),

  • decomposition.npp(x),

  • decomposition.fastica(x).

Alternativly, you can use iTorch notebook and open decomposition.ipynb.
