An Eye into the Future: Leveraging A-Priori Knowledge in Predictive Business Process Monitoring
Name
Anton Yeshchenko
Abstract
Predictive business process monitoring aims at leveraging past process execution data to predict how ongoing (uncompleted) process executions will unfold up to their completion. Nevertheless, cases exist in which, together with past
execution data, some additional knowledge (a-priori
knowledge) about how a process execution will develop in the future is available. This knowledge about the future can be leveraged for
improving the quality of the predictions of events that are currently unknown. In this thesis, we present two techniques - based on Recurrent Neural Networks with Long Short-Term Memory (LSTM) cells - able to leverage knowledge about the structure of the process execution traces as well as a-priori knowledge about how they will unfold in the future for predicting the sequence of future activities of ongoing process executions. The results obtained by applying these techniques on six real-life logs show an improvement in terms of accuracy over a plain LSTM-based baseline.
