Review of Phylogenetic Tree Construction
Motivation: Phylogenetic tree construction is a complex yet important problem in the field of bioinformatics. Once constructed, a phylogenetic or evolutionary tree can lend insight into the evolution of different species. The issue is that for a large number of species the problem grows to a computational complexity that is not easily solved. For this reason, new methods are being researched an...
متن کاملChapter 5 Phylogenetic Tree Construction
The problem in phylogenetic tree construction, is to find the tree which best describes the relationship between a set of objects. We are mostly interested in the case when the objects are species or taxa. carrot whale chimpanzee human Figure 5.1: Phylogenetic tree of 4 species Phylogenetic Tree Construction is based on Cladistics, the systematic classification of groups of organisms on the bas...
متن کاملUsing invariants for phylogenetic tree construction
Phylogenetic invariants are certain polynomials in the joint probability distribution of a Markov model on a phylogenetic tree. Such polynomials are of theoretical interest in the field of algebraic statistics and they are also of practical interest — they can be used to construct phylogenetic trees. This paper is a self-contained introduction to the algebraic, statistical, and computational ch...
متن کاملMetric learning for phylogenetic tree construction
We introduce new methods for phylogenetic tree construction by using metric learning to optimize the power of phylogenetic invariants on trees with four leaves. Phylogenetic invariants are polynomials in the joint probabilities which vanish under a model of evolution on a phylogenetic tree. They have been used for tree construction with only partial success partly because a good scoring metric ...
متن کاملAlgorithms for efficient phylogenetic tree construction
The gene-duplication problem is to infer a species supertree from a collection of gene trees that are confounded by complex histories of gene duplications. This problem is NP-hard and thus requires efficient and effective heuristics. Existing heuristics perform a stepwise search of the tree space, where each step is guided by an exact solution to an instance of a local search problem. These loc...
