WebThe minimum data needed for process mining are two columns that record: Activity: The activities (or events) that took place in the process. Date: The date (and perhaps time) each activity occurred. For example, knowing how and when a complaint is handled in different ways are the two minimum pieces of information needed for process mining in data. WebThese DCP strategies along with their conditions allow the FCHM algorithm (Fournier-Viger et al., Citation 2024) to gain better performance compared with those of the FHM algorithm (Fournier-Viger et al., Citation 2014).
