Anytime univariate STAMP algorithm Parallel version

Source: R/stamp-par.R, R/stamp.R

Computes the best so far Matrix Profile and Profile Index for Univariate Time Series.

stamp_par(
  ...,
  window_size,
  exclusion_zone = getOption("tsmp.exclusion_zone", 1/2),
  verbose = getOption("tsmp.verbose", 2),
  s_size = Inf,
  n_workers = 2,
  weight = NULL
)

stamp(
  ...,
  window_size,
  exclusion_zone = getOption("tsmp.exclusion_zone", 1/2),
  verbose = getOption("tsmp.verbose", 2),
  s_size = Inf,
  weight = NULL
)

Arguments

...

a matrix or a vector. If a second time series is supplied it will be a join matrix profile.

window_size

an int. Size of the sliding window.

exclusion_zone

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

verbose

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

s_size

a numeric. for anytime algorithm, represents the size (in observations) the random calculation will occur (default is Inf).

n_workers

an int. Number of workers for parallel. (Default is 2).

weight

a vector of numeric or NULL with the same length of the window_size. This is a MASS extension to weight the query.

Value

Returns a MatrixProfile object, a list with the matrix profile mp, profile index pi

left and right matrix profile lmp, rmp and profile index lpi, rpi, window size w and exclusion zone ez.

Details

The Matrix Profile, has the potential to revolutionize time series data mining because of its generality, versatility, simplicity and scalability. In particular it has implications for time series motif discovery, time series joins, shapelet discovery (classification), density estimation, semantic segmentation, visualization, rule discovery, clustering etc. The anytime STAMP computes the Matrix Profile and Profile Index in such manner that it can be stopped before its complete calculation and return the best so far results allowing ultra-fast approximate solutions. 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. exclusion_zone is used to avoid trivial matches; if a query data is provided (join similarity), this parameter is ignored.

Functions

  • stamp_par(): Parallel version.

  • stamp(): Single thread version.
