kd_tree FAST NEAREST NEIGHBORS SEARCH

here are some programs that we use for fast nearest neighbor search:

kd_partition.m -- partitions multivariate data into a kd-tree.

kd_search.m -- search the kd-tree created by kd_partition.m.

these are some specialized partitioning and searching programs that we use in phase space warping applications:

kb_box_part.m -- partition data space into a set number of boxes.

kd_box_search.m -- find which box a query point belongs to.

NTSA
NONLINEAR TIME SERIES ANALYSIS

these are some of the programs that are of general use in nonlinear time series analysis:.

ami.m -- estimates average mutual information for time series (usually used to estimate delay time for delay coordinate embedding), which also needs these: cond_prob.m and joint_prob.m -- conditional and joint probabilities for two scalar variables.

fnns.m -- false nearest neighbors search for estimating smallest sufficient embedding dimension for delay coordinate embedding (which also needs kd_partition.m and kd_search.m).

reconst_ps.m -- reconstructs the phase space using delay coordinate embedding after appropriate delay time and embedding dimension are determined.

apwd.m -- calculates the curves for estimating the average pointwise dimension of the data (needs kd_partition.m and kd_search.m).


PSW

PHASE SPACE WARPING

these are programs for calculating PSW-based metrics and feature vectors:

pswtm.m -- phase space warping tracking metric estimation.

psw_cont.m -- phase space warping feature vector estimation.

protocol.m -- sample protocol, just for an example.

SOD SMOOTH ORTHOGONAL DECOMPOSITION

these are some of the programs...
