Quality dimensions: precision and generalization

Hello!
I want to compute generalization value but I don't know what is the best algorithm to use.
I compute fitness by using on ProM “Partial Aware Replay” plug-in of Lu and precision by using “Check Precision based on Align-ETConformance” plug-in of Munoz-Gama.  Unfortunately, when I try to use “Measure Precision/Generalization” of Adriansyah plug-in to calculate  precision and generalization values, it doesn't give me any result.

Thanks in advance for your help.

  • Dear Elisa,

    Thanks for your question.

    The  plug-in “Measure Precision/Generalization” of Adriansyah needs a log, a petri net and an alignment as input. I discovered a model from an input log using the plugin "Mine Petri net with Inductive Miner" and created an alignment using the plugin "Replay a log on Petri Net for Conformance Analysis". Then with the input log, the discovered model and the created alignment as input, the plugin  “Measure Precision/Generalization” works well.

    If you have more questions, please let me know.

  • Thanks for your reply and for your help. I'll try to use the plugin "Replay a log on Petri Net for conformance analysis", before using the plugin "Measure Precision/Generalization".
    Furthermore, i wonder if it is possible to evaluate  quality dimensions (fitness, precision, generalization and simplicity) of the Fuzzy model obtained from Fuzzy Miner or to convert the Fuzzy model to a Petri Net.
    Thanks again for the help

  • Hi Elisa,

    Since the Fuzzy model does not have semantics (e.g. a choice between two activities is modeled in the same way as two activities in parallel) a translation is not possible. Therefore the four quality dimensions are also not defined for Fuzzy models.

  • Hi,

    Thanks for your suggestions.

    I would need more information.

    How are  precision and generalization values calculated by the plug-in  "Measure Precision/Generalization" ? Is there any papers available on this subject?

    Are there any alternative plug-in available on ProM to calculate generalization and precision values?

    Thanks in advance for your help.
