get_pc_space {oddstream} | R Documentation |
Define a feature space using the PCA components of the feature matrix
Description
Define a two dimensional feature space using the first two principal components generated from
the fetures matrix returned by extract_tsfeatures
Usage
get_pc_space(features, robust = TRUE, kpc = 2)
Arguments
features |
Feature matrix returned by |
robust |
If TRUE, a robust PCA will be used on the feature matrix. |
kpc |
Desired number of components to return. |
Value
It returns a list with class 'pcattributes' containing the following components:
pcnorm |
The scores of the firt kpc pricipal components |
center , scale |
The centering and scaling used |
rotation |
the matrix of variable loadings (i.e., a matrix whose columns contain the eigenvectors).
