Accounting for Observational Uncertainty in Forecast Verification: An Information-Theoretical View on Forecasts, Observations, and Truth

Steven V. Weijs, Nick van de Giesen
2011 Monthly Weather Review  
Recently, an information-theoretical decomposition of Kullback-Leibler divergence into uncertainty, reliability, and resolution was introduced.  ...  In this article, this decomposition is generalized to the case where the observation is uncertain.  ...  The authors thank the Royal Netherlands Meteorological Office (KNMI) and Meteo Consult for kindly providing the forecast and observation data that was used for this research.  ...

Mining Uncertain Event Data in Process Mining

Marco Pegoraro, Wil M.P. van der Aalst
2019 2019 International Conference on Process Mining (ICPM)  
Finally, we show how upper and lower bounds for conformance can be obtained aligning an uncertain trace onto a regular process model.  ...  In this paper we analyze the previously unexplored setting of uncertain event logs: logs where quantified uncertainty is recorded together with the corresponding data.  ...  Uncertainty has been represented in the XES standard through meta-attributes and constructs such as lists, such that any XES importer can read an uncertain log file.  ...

Mining Process Model Descriptions of Daily Life Through Event Abstraction [chapter]

N. Tax, N. Sidorova, R. Haakma, W. van der Aalst
2017 Studies in Computational Intelligence  
We present a framework for the extraction of features that can be used for abstraction with supervised learning methods that is based on the XES IEEE standard for event logs.  ...  This framework can automatically abstract sensor-level events to their interpretation at the human activity level, after training it on training data for which both the sensor and human activity events  ...  XES, which is an abbreviation for eXtensible Event Stream, is the IEEE standard for process mining event logs. An overview of the XES file structure which is shown in Figure 2 .  ...

Time Resource Networks [article]

Szymon Sidor, Peng Yu, Cheng Fang, Brian Williams
2016 arXiv   pre-print
We address such problems by introducing the Time Resource Network (TRN), an encoding for resource-constrained scheduling problems.  ...  We propose two algorithms for determining the consistency of a TRN: one based on Mixed Integer Programing and the other one based on Constraint Programming, which we evaluate on scheduling problems with  ...  [Vidal and Ghallab, 1996] defined an uncertain temporal constraint, where the duration between two time events can take a value from an interval [l, u] , which is unknown during the time of scheduling  ...

Using system context information to complement weakly labeled data [article]

Matthias Meyer, Michaela Wenner, Clément Hibert, Fabian Walter, Lothar Thiele
2021 arXiv   pre-print
Based on real-world data we show that this approach leads to an increased accuracy in case of weakly labeled data and leads to an increased robustness and transferability of the classifier to new sensor  ...  Real-world datasets collected with sensor networks often contain incomplete and uncertain labels as well as artefacts arising from the system environment.  ...  Therefore, an extensive dataset is usually available for training albeit not always thoroughly annotated.  ...
