LS-ICE: A Load State Intercase Encoding framework for improved predictive monitoring of business processes

Preprocessed publicly available event logs for the article "LS-ICE: A Load State Intercase Encoding framework for improved predictive monitoring of business processes".

AbstractResearch on developing techniques for predictive process monitoring has generally relied on feature encoding schemes that extract intracase features from events to make predictions. In doing so, the processing of cases is assumed to be solely influenced by the attributes of the cases themselves. However, cases are not processed in isolation and can be influenced by the processing of other cases or, more generally, the state of the process under investigation. In this work, we propose the LS-ICE (load state intercase encoding) framework for encoding intercase features that enriches events with a depiction of the state of relevant load points in a business process. To assess the benefits of the intercase features generated using the LS-ICE framework, we compare the performance of predictive process monitoring models constructed using the encoded features against baseline models without these features. The models are evaluated for remaining trace and runtime prediction using five real-life event logs. Across the board, a consistent improvement in performance is noted for models that integrate intercase features encoded through the proposed framework, as opposed to baseline models that lack these encoded features.
