TSCompute_LCSS_Dist and TSCompute_Normalized_LCSS_Dist functions

The TSCompute_LCSS_Dist and TSCompute_Normalized_LCSS_Dist functions calculate the longest common subsequence distance between two time series sequences.

Syntax

TSCompute_LCSS_Dist (
                 sequence1        list,
                 sequence2        list,
                 normalize_delta  DOUBLE PRECISION,                      
                 epsilon          DOUBLE PRECISION) 
RETURNS DOUBLE PRECISION

TSCompute_Normalized_LCSS_Dist (
                 sequence1        list,
                 sequence2        list,
                 normalize_delta  DOUBLE PRECISION,                      
                 epsilon          DOUBLE PRECISION) 
RETURNS DOUBLE PRECISION

sequence1: A list of values that is returned by the ValueAsCollection or TSGetValueList function.
sequence2: A list of values that is returned by the ValueAsCollection or TSGetValueList function.
normalized_delta: The limit of the delta distance.
epsilon: The value of ϵ in the longest common subsequence formula.

Usage

Run the TSCompute_LCSS_Dist or TSCompute_Normalized_LCSS_Dist function to use the longest common subsequence algorithm to calculate the distance between two time series sequences. The TSCompute_LCSS_Dist function returns the actual distance. The TSCompute_Normalized_LCSS_Dist function returns the distance as a value 0.0 - 1.0. See Longest common subsequence.

Returns

A number that represents the difference between two sequences.
