Implement inter-arrival EMD #5

Closed david-chapela closed 1 year ago

david-chapela commented 1 year ago

Implement function to compare the (case) inter-arrival times of two event logs with the EMD.

  1. Compute the arrival timestamp for each process instance (its first start time).
  2. Compute the inter-arrival times (i.e., the interval of time from each arrival time and the next one).
  3. Group the inter-arrival times in bins by a given bin size (time gap).
  4. Compare the discretized histograms of the two event logs with the Wasserstein Distance (a.k.a. EMD).
