Abstract

A current trend in predictive business process monitoring is to construct predictive models using deep neural networks (DNNs), especially long short-term memory neural networks, convolutional neural networks, or multilayer perceptron neural networks. While these DNN types typically require data defined on the Euclidean space (e.g., grids), graph neural networks (GNNs), a relatively new type of DNNs, can compute data defined on the non-Euclidean space (e.g., graphs). Because GNNs can directly compute graph-oriented data inputs, generally structured into nodes and edges, they can explicitly model event relationships. This paper investigates gated graph sequence neural networks (GGNNs) for the next activity prediction. First results with two real-life event logs show that GGNNs can outperform traditional DNNs regarding predictive quality, especially if nodes of an input graph are assumed as events, and the graph’s adjacency matrix only describes event relationships of a process instance prefix.
