About ETM

TangYahuiTangYahui Posts: 59
Hello everyone, I change the ETM code that it can makes some process trees and a event log as inpout,(process trees is randomly generated originally). But I find that this code can only handle process tree which left nodes cotain "...start+" and "..complete+",and each "start"correspond to a"complete",if the input process tree’s format is not like this,the program error happens. The errors is like this: java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Fitness evaluation task execution failed. How can I solve this question?I find that Some event log contain only "complete+"class,does it means that I can not handle them use ETM? Thank you in advance! TangYahui

    This is set in the classifier used. In the ETMParam object you can set this. For instance change it to the NameClassifier (from XLogInfo). Good luck!

    Hi Joos,
     I have find the ETMParam object in my code,but I still don't know how to change it,and I also find that in prom as follows.Should they be the same?
     And this is the event log I use:http://data.4tu.nl/repository/uuid:c45dcbe9-557b-43ca-b6d0-10561e13dcb5
    In order to run it correctly,which classifier should I choose?
    Sorry if my question is too basic。 
    Thank you again.

    Hi Tanyahui,

    I don't have the code at hand but the ETMParam object should have a .setClassifier method or similar. Just pass the XLogInfoImpl.NameClassifier to this method and it should work.

    In your screenshot this classifier is the 'Event name' classifier.
