Hipparcos Variable Star Detection and Classification Efficiencyby comparing the results with prior knowledge coming from the catalog or from the literature. A combination of two variability criteria is applied in the first step to select 17,006 variability candidates from a complete sample of 115,152 stars. Our candidate sample turns out to include 10,406 known

Efficient Calculation of Covariances for Astrometric Data in the Gaia Catalogueuting quantities that combine multiple catalogue parameters. The computation and storage of the full covariance matrix for the expected 5 ×10. astrometric parameters (∼10. TeraByte) is, however, expected to be infeasible considering near-future storage and floating-point capabilities. In this paper

Bayesian Analysis of Cosmic Structures which arise due to the non-Gaussian character of the Galaxy and matter distribution. In particular, we investigate the advantages and limitations of the Poisson-lognormal model and discuss how to extend this work. With the lognormal prior using the Hamiltonian sampling technique and on scales of ab

Classification of Poorly Time Sampled Light Curves of Periodic Variable Starsfollow-up. In practice, labeled light curves from catalogs with hundreds of flux measurements (the training set) may be used to classify curves from ongoing surveys with tens of flux measurements (the test set). Statistical classifiers generally assume that the probability of class given light curve

Handling Imbalanced Data Sets in Multistage Classificationclassification problem is divided into several sequential steps, each one associated to a single classifier that works with subgroups of the original classes. In each level, the current set of classes is split into smaller subgroups of classes until they (the subgroups) are composed of only one clas

Recent Advances in Cosmological Bayesian Model Comparisonon of the Bayesian evidence, the central quantity for Bayesian model comparison, and present applications to inflationary model building and to constraining the curvature and minimum size of the Universe. I conclude by discussing what I think are some of the open challenges in the field.
