Computes the Laplacian Eigenmap For Dimension Reduction

Takes a n-D Takens' Embedding and returns the 2-D Laplacian Eigenmap.

computeLaplacianEmbedding(takens)

Arguments

takens	a data.frame of the n-dimensional Takens' embedding. Columns defined from (1-D to n-D). TimeCycle defaults to n = 3.

Value

a data.frame of the 2-dimensional Takens' embedding. Columns defined by eigen vectors with last two non-trivial eigen values.
