Robust Drift Characterization from Event Streams of Business Processes

Alireza Ostovar, Sander J. J. Leemans, Marcello La Rosa
2020 ACM Transactions on Knowledge Discovery from Data  
To address the above limitations, this paper proposes a robust, automated method for charactering process drifts from event streams.  ...  As such, a number of techniques have been developed to detect process drifts, i.e. statistically significant changes in process behavior, from process event logs (offline) or event streams (online).  ...  ACKNOWLEDGMENTS We thank Abderrahmane Maaradji for his feedback on early versions of this paper. This research is partly funded by the Australian Research Council (grant DP150103356).  ...

A Survey on Concept Drift in Process Mining

Denise Maria Vecino Sato, Sheila Cristiana De Freitas, Jean Paul Barddal, Edson Emilio Scalabrin
2022 ACM Computing Surveys  
Concept drift in process mining (PM) is a challenge as classical methods assume processes are in a steady-state, i.e., events share the same process version.  ...  Existing works depict that (i) PM still primarily focuses on offline analysis, and (ii) the assessment of concept drift techniques in processes is cumbersome due to the lack of common evaluation protocol  ...  ACKNOWLEDGMENTS The authors would like to thank the support and funding of this research by CAPES Coordenação de Aperfeiçoamento de Pessoal de Nível Superior -Brasil (CAPES) -Finance Code 001 under Grant  ...

A Robust and Accurate Approach to Detect Process Drifts from Event Streams [article]

Yang Lu, Qifan Chen, Simon Poon
2021 arXiv   pre-print
Business processes are bound to evolve as a form of adaption to changes, and such changes are referred as process drifts.  ...  The proposed method can accurately detect drift points from event logs and is robust to noises. Both artificial and real-life event logs are used to evaluate our method.  ...  We focus on offline process drift detection from the control-flow perspective. We propose an event-stream based process drift detection method which is accurate, robust to noise and reasonably fast.  ...
