A study of online and blockwise updating of the EM algorithm for Gaussian mixtures (2014)
Presentation / Conference Contribution
Einbeck, J., & Bonetti, D. (2014, July). A study of online and blockwise updating of the EM algorithm for Gaussian mixtures. Presented at 29th International Workshop on Statistical Modelling, Göttingen

A variant of the EM algorithm for the estimation of multivariate Gaussian mixtures, which allows for online as well as blockwise updating of sequentially obtained parameter estimates, is investigated. Several dierent update schemes are considered and... Read More about A study of online and blockwise updating of the EM algorithm for Gaussian mixtures.

Bayesian shape modelling of cross-sectional geological data (2014)
Presentation / Conference Contribution
Tsiftsi, T., Jermyn, I., & Einbeck, J. (2014, July). Bayesian shape modelling of cross-sectional geological data. Presented at 29th International Workshop on Statistical Modelling, Göttingen

Shape information is of great importance in many applications. For example, the oil-bearing capacity of sand bodies, the subterranean remnants of ancient rivers, is related to their cross-sectional shapes. The analysis of these shapes is therefore of...

Bivariate Estimation of Distribution Algorithms for Protein Structure Prediction (2014)
Presentation / Conference Contribution
Bonetti, D., Delbem, A., & Einbeck, J. (2014, December). Bivariate Estimation of Distribution Algorithms for Protein Structure Prediction. Presented at 29th International Workshop on Statistical Modelling, Göttingen, Germany

A real-valued bivariate ‘Estimation of Distribution Algorithm’ specific for the ab initio and full-atom Protein Structure Prediction problem is proposed. It is known that this is a multidimensional and multimodal problem. In order to deal with the mu... Read More about Bivariate Estimation of Distribution Algorithms for Protein Structure Prediction.

Implementation of a local principal curves algorithm for neutrino interaction reconstruction in a liquid argon volume. The European Physical Journal C, 74(3), Article 2832. https://doi.org/10.1140/epjc/s10052-014-2832-4

A local principal curve algorithm has been implemented in three dimensions for automated track and shower reconstruction of neutrino interactions in a liquid argon time projection chamber. We present details of the algorithm and characterise its perf... Read More about Implementation of a local principal curves algorithm for neutrino interaction reconstruction in a liquid argon volume.
