Dependency type based on Flexible Heuristics Miner (FHM)

Computes the dependencies based on the approach known as Flexible Heuristics Miner.

dependency_type_fhm(
  threshold_dependency = 0.9,
  threshold_l1 = threshold_dependency,
  threshold_l2 = threshold_dependency,
  threshold_frequency = 0,
  all_connected = FALSE,
  endpoints_connected = FALSE
)

Arguments

threshold_dependency

A dependency threshold, usually in the interval [0,1], filtering out dependencies below the threshold.

threshold_l1

A dependency threshold, usually in the interval [0,1], filtering out self-loop dependencies below the threshold.

threshold_l2

A dependency threshold, usually in the interval [0,1], filtering out length-two loop dependencies below the threshold.

threshold_frequency

An absolute frequency threshold filtering dependencies which are observed infrequently.

all_connected

If TRUE the best antecedent and consequent (as determined by the dependency measure) are going to be added regardless of the threshold value.

endpoints_connected

If TRUE the start/end activity is added as antecedent/consequent when an activity would not be connected according to the threshold value.

Value

A dependency type.
