Taxic Homology 5 Overall Similarity
Modified three-taxon analysis (m3ta), a method in which three-taxon statements are produced from a nonadditive binary coding of the original data, has been proposed as a model-free way of assessing monophyly of groups, utilizing the taxic concept of homology. In fact the taxic concept amounts to a model, and, further, one that seems to conflict directly with evolution. M3ta is a type of groupin...
متن کاملTaxic homology and three-taxon statement analysis.
Three-taxon statement analysis (3TA) and standard cladistic analysis (SCA) were evaluated relative to propositions of taxic homology. There are definite distinctions between complement relation homologs and paired homologs. The complement relation is discussed, relative to rooting, parsimony, and taxic propositions of homology. The complement relation, as implemented in SCA, makes sense only be...
متن کاملImpulsivity and Overall Similarity Classification
It is sometimes argued that implementation of an overall similarity classification is less effortful than implementation of a single-dimension classification. One piece of evidence taken to be in support of this argument is that highly impulsive individuals appear to be more likely to sort on the basis of overall similarity than individuals with low impulsivity (Ward, 1983); presumably, higher ...
متن کاملAn Introduction to Sequence Similarity (“Homology”) Searching
Sequence similarity searching, typically with BLAST, is the most widely used and most reliable strategy for characterizing newly determined sequences. Sequence similarity searches can identify “homologous” proteins or genes by detecting excess similarity— statistically significant similarity that reflects common ancestry. This unit provides an overview of the inference of homology from signific...
متن کاملPersistent homology and partial similarity of shapes
The ability to perform shape retrieval based not only on full similarity, but also partial similarity is a key property for any content-based search engine. We prove that persistence diagrams can reveal a partial similarity between two shapes by showing a common subset of points. This can be explained using the MayerVietoris formulas that we develop for ordinary, relative and extended persisten...
