Fast Low-cost Unipotent Semantic Segmentation (FLUSS)

Source: R/fluss.R

FLUSS is a Domain Agnostic Online Semantic Segmentation that uses the assumption that when few arc are crossing a given index point, means that there is a high probability of semantic change. This function is a wrap to fluss_cac() and fluss_extract().

fluss(.mp, num_segments = 1, exclusion_zone = NULL)

Arguments

.mp

a MatrixProfile object.
num_segments

an int. Number of segments to extract. Based on domain knowledge.
exclusion_zone

if a number will be used instead of embedded value. (Default is NULL).

Value

Returns the input .mp object new names: cac, corrected arc count and fluss with the location of semantic changes.
