Canonical Divergence Analysis
We aim to analyze the relation between two random vectors that may potentially have both different number of attributes as well as realizations, and which may even not have a joint distribution. This problem arises in many practical domains, including biology and architecture. Existing techniques assume the vectors to have the same domain or to be jointly distributed, and hence are not applicab...
متن کاملAn analysis of genetic variation and divergence in Indian tropical polyvoltine silkworm (Bombyx mori L.) genotypes
The genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. The results revealed that the single shell weight showed higher genetic variation such as PCV% (17.20%), GCV% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. The D2 (Mahalonobis? distance) statistics reveal...
متن کاملPhylogenetic analysis of HSP70 gene of Aspergillus fumigatus reveals conservation intra-species and divergence inter-species
Aspergillus fumigatus is a saprophyte fungus, widely spread in a variety of ecologicalniches and the most prevalent aspergilli responsible for human and animal invasiveaspergillosis. The first step to develop novel and efficient therapies is the identificationand understanding of the key tolerance and virulence factors of pathogens. The mainfocus of the present study is to perform the similarit...
متن کاملDating divergence of Polystigma and other Sordariomycetes
Studies on the evolutionary history of ascomycetes in terms of time scale will help to understand historical patterns that shape their biodiversity. Until now most of dating studies of ascomycetes have focused on major events in fungal evolution but not on divergence events within smaller groups of fungi e.g. within Sordariomycetes. We used molecular dating to estimate the time of separation of...
متن کاملFactor analysis models via I-divergence optimization
Given a positive definite covariance matrix [Formula: see text] of dimension n, we approximate it with a covariance of the form [Formula: see text], where H has a prescribed number [Formula: see text] of columns and [Formula: see text] is diagonal. The quality of the approximation is gauged by the I-divergence between the zero mean normal laws with covariances [Formula: see text] and [Formula: ...
