Predictive Process Monitoring Using Object-centric Graph Embeddings

Object-centric predictive process monitoring explores and utilizes object-centric event logs to enhance process predictions. The main challenge lies in extracting relevant information and building effective models. In this paper, we propose an end-to-end model that predicts future process behavior, focusing on two tasks: next activity prediction and next event time. The proposed model employs a graph attention network to encode activities and their relationships, combined with an LSTM network to handle temporal dependencies. Evaluated on one real-life and three synthetic event logs, the model demonstrates competitive performance compared to state-of-the-art methods.
