lol.project.lrcca {lolR}

Low-rank Canonical Correlation Analysis (LR-CCA)

Description

A function for implementing the Low-rank Canonical Correlation Analysis (LR-CCA) Algorithm.

Usage

lol.project.lrcca(X, Y, r, ...)

Arguments

X

[n, d] the data with n samples in d dimensions.

Y

[n] the labels of the samples with K unique labels.

r

the rank of the projection.

...

trailing args.

Value

A list containing the following:

A

[d, r] the projection matrix from d to r dimensions.

d

the eigen values associated with the eigendecomposition.

ylabs

[K] vector containing the K unique, ordered class labels.

centroids

[K, d] centroid matrix of the K unique, ordered classes in native d dimensions.

priors

[K] vector containing the K prior probabilities for the unique, ordered classes.

Xr

[n, r] the n data points in reduced dimensionality r.

cr

[K, r] the K centroids in reduced dimensionality r.

Examples

library(lolR)
data <- lol.sims.rtrunk(n=200, d=30)  # 200 examples of 30 dimensions
X <- data$X; Y <- data$Y
model <- lol.project.lrcca(X=X, Y=Y, r=5)  # use lrcca to project into 5 dimensions
