Taming Discrete Integration via the Boon of Dimensionality [article]

Jeffrey M. Dudek, Dror Fried, Kuldeep S. Meel
2020 arXiv   pre-print
The key contribution of this work addresses this scalability challenge via an efficient reduction of discrete integration to model counting.  ...  We augment our proposed reduction, called DeWeight, with a state of the art efficient approximate model counter and perform detailed empirical analysis over benchmarks arising from neural network verification  ...  Acknowledgements We are grateful to Supratik Chakraborty and Moshe Vardi for many insightful discussions.  ...

Case Study for the Return on Investment of Internet of Things Using Agent-Based Modelling and Data Science

Charles Houston, Stephen Gooberman-Hill, Richard Mathie, Andrew Kennedy, Yunxi Li, Pedro Baiz
2017 Systems  
Agent-based modelling, through an integration with data science, presents an attractive simulation method to capture these underlying complexities and provide a solution.  ...  Traditional simulation and analysis techniques cannot model the complex systems inherent in fields such as infrastructure asset management, or suffer from a lack of data on which to build a prediction.  ...  Note that only the data gathered from January 1, 2012 contained the fields required to categorise the failures in this way and entries with missing failure labels were excluded.  ...

Partially Ordered Mixed Hidden Markov Model for the Disablement Process of Older Adults

Edward Ip, Qiang Zhang, Jack Rejeski, Tammy Harris, Stephen Kritchevsky
2013 Journal of the American Statistical Association  
We describe a maximum likelihood method for estimating the partially ordered, mixed effects model and show how the model can be applied to a longitudinal data set that consists of N = 2,903 older adults  ...  The model generalizes the continuation ratio model for ordinal data in the generalized linear model literature and provides a formal framework for testing the effects of risk factors and/or an intervention  ...  the original data set as an anchor model, and for each imputed data set we determined a state label by matching the state to the closest state in the anchor model.  ...

The quickhull algorithm for convex hulls

1996 ACM Transactions on Mathematical Software  
To determine the Delaunay triangulation of a set of points lift the points to a paraboloid and compute their convex hull.  ...  We represent a convex hull with a set of facets and a set of adjacency lists giving the neighbors and vertices for each facet. The boundary elements of a facet are called ridges.  ...  ACKNOWLEDGMENTS Albert Marden and Victor Milenkovic provided excellent environments for completing this work. The referees' comments greatly improved the presentation and content of this article.  ...
