Multivariate Approaches to Classification in Extragalactic Astronomy

Autor: Fraix-Burnet, Didier, Thuillard, Marc, Chattopadhyay, Asis Kumar

Publikováno v: Frontiers in Astronomy and Space Sciences, Lee Samuel Finn, 2015, 2 (3), pp.00

Clustering objects into synthetic groups is a natural activity of any science. Astrophysics is not an exception and is now facing a deluge of data. For galaxies, the one-century old Hubble classification and the Hubble tuning fork are still largely i

A six-parameter space to describe galaxy diversification

Autor: Fraix-Burnet, Didier, Chattopadhyay, Tanuka, Chattopadhyay, Asis Kumar, Davoust, Emmanuel, Thuillard, Marc

Publikováno v: Astronomy and Astrophysics (2012) --

Galaxy diversification proceeds by transforming events like accretion, interaction or mergers. These explain the formation and evolution of galaxies that can now be described with many observables. Multivariate analyses are the obvious tools to tackl

Report

Phylogenetic Applications of the Minimum Contradiction Approach on Continuous Characters

Autor: Thuillard, Marc, Fraix-Burnet, Didier

Publikováno v: Evolutionary Bioinformatics 5 (2009) 33-46

We describe the conditions under which a set of continuous variables or characters can be described as an X-tree or a split network. A distance matrix corresponds exactly to a split network or a valued X-tree if, after ordering of the taxa, the varia
