Assessing the accuracy of ancestral protein reconstruction methods.

PLoS Computational Biology, 2006
The phylogenetic inference of ancestral protein sequences is a powerful technique for the study of molecular evolution, but any conclusions drawn from such studies are only as good as the accuracy of the reconstruction method.

A flexible ancestral genome reconstruction method based on gapped adjacencies [PDF]

BMC Bioinformatics, 2012
Background The "small phylogeny" problem consists in inferring ancestral genomes associated with each internal node of a phylogenetic tree of a set of extant species.

Comparing the ancestral and traditional methods of sparkling wine production

IVES Technical Reviews
Ancestral sparkling wine production has seen an increase in recent years. Under the label “ancestral method” consumers can find a wide variety of products, as each producer follows their own interpretation of the process without standardised guidelines.

Analysis on the reconstruction accuracy of the Fitch method for inferring ancestral states [PDF]

BMC Bioinformatics, 2011
Background As one of the most widely used parsimony methods for ancestral reconstruction, the Fitch method minimizes the total number of hypothetical substitutions along all branches of a tree to explain the evolution of a character. Due to the extensive

A Novel Method for Aggregation of Bayesian Networks without Considering an Ancestral Ordering

Applied Artificial Intelligence, 2018
A good method of combining Bayesian networks (BNs) should be a generic one that ensures a combined BN meets three important criteria of avoiding cycles, preserving conditional independencies, and preserving the characteristics of individual BN parameters.

Ancestral polymorphisms in Drosophila pseudoobscura and Drosophila miranda [PDF]

, 2011
Ancestral polymorphisms are defined as variants that arose by mutation prior to the speciation event that generated the species in which they segregate. Their presence may complicate the interpretation of molecular data and lead to incorrect phylogenetic

Evaluation of methods for estimating coalescence times using ancestral recombination graphs [PDF]

Genetics, 2021
Abstract The ancestral recombination graph is a structure that describes the joint genealogies of sampled DNA sequences along the genome. Recent computational methods have made impressive progress toward scalably estimating whole-genome genealogies.

A comparison of ancestral state reconstruction methods for quantitative characters [PDF]

Journal of Theoretical Biology, 2016
Abstract Choosing an ancestral state reconstruction method among the alternatives available for quantitative characters may be puzzling. We present here a comparison of five of them, namely the maximum likelihood, restricted maximum likelihood, generalized least squares, phylogenetic independent contrasts and squared parsimony methods.

A Fast Likelihood Method to Reconstruct and Visualize Ancestral Scenarios [PDF]

Molecular Biology and Evolution, 2018
Abstract The reconstruction of ancestral scenarios is widely used to study the evolution of characters along a phylogenetic tree. In the likelihood framework one commonly uses the marginal posterior probabilities of the character states, and the joint reconstruction of the most likely scenario.

Ancestral Instrument Method for Causal Inference without Complete Knowledge

Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence, 2022
Unobserved confounding is the main obstacle to causal effect estimation from observational data. Instrumental variables (IVs) are widely used for causal effect estimation when there exist latent confounders. With the standard IV method, when a given IV is valid, unbiased estimation can be obtained, but the validity requirement on a standard IV is ...
