Predicting Activities in Business Processes with LSTM Recurrent Neural Networks
Description
The Long Short-Term Memory (LSTM) Recurrent Neural Networks provide a high precision in the prediction of the modeling of sequences in several application domains. This article introduces the use of LSTM networks for the prediction of activities in a business process. This is a key aspect to provide valuable input for planning and resource allocation. Predicting the behavior of a business process is possible by exploiting event logs to make predictions about execution of cases. Each trace associated with a case indicate the sequential execution of activities. A methodology for the implementation of the LSTM network in the process mining domain is also proposed. An event log of the industry domain is used to train and test the proposed LSTM neural network. Our preliminary results indicate that the prediction of the next activity is acceptable according to the literature of the domain.
