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

Description

calls two function Calc_Energy

Usage

JTree_Scores(X, K, Zpos, T, PCidx, maxlev, all_nodes)

Arguments

X

data matrix

K

number of vectors in final representation

Zpos

Zpos[J,2] is the nodes to be merged

T

a list containing T nodes. Element in the cell array contains a 2-by-2 matrix that decorrelates inputs X(:,Z (k,1)) and X(:,Z(k,2)); output from LKLB_Decorrelate.

PCidx

PCidx[J,2] id of principal components (1st or 2nd)

maxlev

default:dim-1

all_nodes

node labels, output of Build_JTree

Value

• levels
  at each level
• scores
  what the score is at the corresponding level
