Description

Returns a SITS table with distances to be used for training in ML methods This is a front-end to the sits_TWDTW_matches whose outout is trimmed down to contain just distances

sits_TWDTW_dist_bands(data.tb = NULL, patterns.tb = NULL,
  dist.method = "euclidean", alpha = -0.1, beta = 100, theta = 0.5,
  span = 250, keep = FALSE, multicores = 1)

Arguments

data.tb

a table in SITS format with a time series to be classified using TWTDW

patterns.tb

a set of known temporal signatures for the chosen classes

dist.method

A character. Method to derive the local cost matrix.

alpha

(double) - the steepness of the logistic function used for temporal weighting

beta

(integer) - the midpoint (in days) of the logistic function

theta

(double) - the relative weight of the time distance compared to the dtw distance

span

minimum number of days between two matches of the same pattern in the time series (approximate)

keep

keep internal values for plotting matches

multicores

number of threads to process the validation (Linux only). Each process will run a whole partition validation.

Value

matches a SITS table with the information on matches for the data
