⚠️There's a newer version (1.1) of this package.Take me there.

treelet (version 0.3-0)

Treelet

Description

a novel construction of multi-scale bases that extends wavelets to non-smooth signals. Returns a hierarchical tree and a multi-scale orthonormal basis which both reflect the internal structure of the data.

Functions in treelet (0.3-0)

Run_JTree

The function computes the basis representation of the matrix at maxlev

Score_JTree

The function computes the scores for the best K basis, for each level of the tree

JTree_Scores

Calculates scores for the "best K-basis" at each level of the tree

JTree_Basis

Calculates the basis for the Jacobi tree algorithm (one or more iterations)

Build_JTree

Builds a hierarchical/wavelet tree of 2-by-2 Jacobi rotations

draw_tree
