Split support and split conflict randomization tests in phylogenetic inference.

Randomization tests allow the formulation and statistical testing of null hypotheses about the quality of entire data sets or the quality of fit between the data and particular phylogenetic hypotheses. Randomization tests of phylogenetic hypotheses based on the concepts of split support and split conflict are described here, as are tests where splits, rather than the data, are randomly permuted...

Phylogenetic Diversity on Split Networks

In biodiversity conservation, one is interested in selecting a subset of taxa for preservation priority. Phylogenetic diversity (PD) provides a quantitative measure for taxon selection on phylogenetic trees. In particular, PD is the total length of the minimal subtree induced by the selected taxa. Recently, it has been shown that on trees the maximal PD score and the corresponding subset of tax...

Learning and Inference for Hierarchically Split PCFGs

Treebank parsing can be seen as the search for an optimally refined grammar consistent with a coarse training treebank. We describe a method in which a minimal grammar is hierarchically refined using EM to give accurate, compact grammars. The resulting grammars are extremely compact compared to other high-performance parsers, yet the parser gives the best published accuracies on several languag...

Split-critical and uniquely split-colorable graphs

The split-coloring problem is a generalized vertex coloring problem where we partition the vertices into a minimum number of split graphs. In this paper, we study some notions which are extensively studied for the usual vertex coloring and the cocoloring problem from the point of view of split-coloring, such as criticality and the uniqueness of the minimum split-coloring. We discuss some proper...

Split decomposition over an abelian group, Part 2: Group-valued split systems with weakly compatible support

Split-decomposition theory deals with relations between R-valued split systems and metrics. In a previous publication (the first of a series of papers on split decomposition over an abelian group), a general conceptual framework has been set up to study these relationships from an essentially algebraic point of view, replacing metrics by certain more general, appropriately definedmultivariatema...
