However, tree reconstruction criteria like maximum parsimony do not necessarily lead to unique trees and in some cases even fail to recognize the "correct" tree (i.e., the tree on which the data was generated). On the other hand, a recent study has shown that for an alignment containing ...
Phylogenetics has a crucial role in genomic epidemiology. Enabled by unparalleled volumes of genome sequence data generated to study and help contain the COVID-19 pandemic, phylogenetic analyses of SARS-CoV-2 genomes have shed light on the virus’s origins, spread, and the emergence and reproducti...
As in MLCA, the solution for matrix B is obtained using principles of maximum likelihood estimation based on the assumed error structures for X and Y. Also as in MLPCA, a variety of algorithms are employed depending on the nature of the errors assumed. Although the TLS problem has, on ...
In terms of algorithm speed, LSO, DE and RSA are the fastest on all the three benchmark sets, and the runtime of all algorithms is almost linearly related to the maximum iterations. Although the conclusions largely depend on the problem types, we believe that an efficient iteration is ...
As its name suggests, the maximum entropy model is intimately related to probability theory. We now give details on the model in order to understand and implement the objective function being optimized. Let X be the D× N matrix of training data, as before, so that xj is a column vector...
