The CosmoStat laboratory is an interdisciplinary research group based at CEA Saclay, near Paris, France. Its aim of bringing together a team of cosmologists and computer scientists in order to find new ways to approach problems in the domains of astrophysics, cosmology and signal processing. In this blog its talks about the same.
Authors: Euclid Collaboration, R. Adam, ..., S. Farrens, et al. Journal: A&A Year: 2019 Download: ADS | arXiv Abstract Galaxy cluster counts in bins of mass and redshift have been shown to be a competitive probe to test cosmological models. This method requires an efficient blind detection of clusters from surveys with a well-known selection function Read More
Date: July 12th 2019, 11am (tentative) Speaker: Sebastian Rojas Gonzales (KU Leuven) Title: Gaussian processes for simulation optimization Room: TBA Abstract The use of kriging metamodels (also known as gaussian processes) in simulation optimization has become increasingly popular during recent years. The majority of the algorithms so far uses the ordinary (deterministic) kriging approach for Read More
