simple_fast {tsmp}

Compute the join similarity for Sound data

Description

Compute the join similarity for Sound data

Usage

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

Details

verbose changes how much information is printed by this function; 0 means nothing, 1 means text, 2 adds the progress bar, 3 adds the finish sound.

Value

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