simple_fast: Compute the join similarity for Sound data

Description

Compute the join similarity for Sound data

Usage

simple_fast(..., window_size, exclusion_zone = 1/2, verbose = 2)

Arguments

...

a matrix of numeric, where each column is a time series. Accepts list and data.frame too. If a second time series is supplied it will be a join matrix profile.

window_size

an int with the size of the sliding window.

exclusion_zone

a numeric. Size of the exclusion zone, based on window size (default is 1/2).

verbose

an int. See details. (Default is 2).

Value

Returns a SimpleMatrixProfile object, a list with the matrix profile mp, profile index pi, window size w and exclusion zone ez.

Details

verbose changes how much information is printed by this function; 0 means nothing, 1 means text, 2 means text and sound.
