This chapter deals with two fundamental concepts in the preprocessing of event logs: the generation of prefixes and bucketing. It begins by explaining how prefixes (i.e., ongoing trace executions) can be extracted from event logs. Bucketing is then introduced as a preprocessing task that improves the performance of predictive monitoring techniques by grouping together similar prefixes, after which a predictive model is computed for each bucket.

摘要

This chapter deals with two fundamental concepts in the preprocessing of event logs: the generation of prefixes and bucketing. It begins by explaining how prefixes (i.e., ongoing trace executions) can be extracted from event logs. Bucketing is then introduced as a preprocessing task that improves the performance of predictive monitoring techniques by grouping together similar prefixes, after which a predictive model is computed for each bucket.
