Release 6.13.104 of DiSCover

On July 12, version 6.13.104 has been released. Changes when compared to version 6.13.98:

Replaced filter using absolute threshold (pretty useless) with filter based on log skeletons. When setting the threshold to, say, 4, then all discovered constraints with confidence 96% or more are taken into account. Any trace that does not satisfy any of these constraint, will be filtered out. This filter precedes the filter using the relative threshold.
Positive and negative traces are taken into account when using the log-skeleton-based filtering.
Increased scales of the threshold form 0-10 to 0-100.
Using simple weighted average over all metrics instead of the balanced mean and power functions.

The dialog for the Xcavation plugin in this version: Log skeleton filter and metrics run up to 100.

Example

As an example we run the Xcavation plugin on the log of the BPIC 2012 containing only the A and O events using the following configuration:

All possible filter thresholds, but do not use fitness or precision: Simply return the most simple net.

After some minutes, the result is shown:

The discovered simplest net.
The thresholds used for this net were 3 (for the log skeleton filter) and 70 (for the relative filter).

One Reply to “Release 6.13.104 of DiSCover”

Today, I realized that the Xcavator plugin does not set the absolute threshold, which is still used in the DiSCover plugin it calls. As a result, the Xcavator plugin implicitly uses the last value that was set for this threshold, or the default value (1) if it has not been set yet.
