Inferring multiple consensus trees and supertrees using clustering: a review

no code implementations1 Jan 2023 Vladimir Makarenkov, Gayane S. Barseghyan, Nadia Tahiri

Consensus trees and supertrees have been widely used in evolutionary studies to combine phylogenetic information contained in individual gene trees.

SimPlot++: a Python application for representing sequence similarity and detecting recombination

1 code implementation17 Dec 2021 Stéphane Samson, Étienne Lord, Vladimir Makarenkov

Motivation: Accurate detection of sequence similarity and homologous recombination are essential parts of many evolutionary analyses.

UncertaintyFuseNet: Robust Uncertainty-aware Hierarchical Feature Fusion Model with Ensemble Monte Carlo Dropout for COVID-19 Detection

1 code implementation18 May 2021 Moloud Abdar, Soorena Salari, Sina Qahremani, Hak-Keung Lam, Fakhri Karray, Sadiq Hussain, Abbas Khosravi, U. Rajendra Acharya, Vladimir Makarenkov, Saeid Nahavandi

Differently from most of existing studies, which used either CT scan or X-ray images in COVID-19-case classification, we present a simple but efficient deep learning feature fusion model, called UncertaintyFuseNet, which is able to classify accurately large datasets of both of these types of images.

Building alternative consensus trees and supertrees using k-means and Robinson and Foulds distance

no code implementations24 Mar 2021 Nadia Tahiri, Bernard Fichet, Vladimir Makarenkov

We describe a new efficient method for inferring multiple alternative consensus trees and supertrees to best represent the most important evolutionary patterns of a given set of gene phylogenies.

Accurate deep learning off-target prediction with novel sgRNA-DNA sequence encoding in CRISPR-Cas9 gene editing

no code implementations 10.1093/bioinformatics/btab112 2021 Jeremy Charlier, Robert Nadon, Vladimir Makarenkov

Results: In our experiments, we compare the proposed sgRNA-DNA sequence encoding applied in a deep learning prediction framework with state-of-the-art encoding and prediction methods.

XtracTree: a Simple and Effective Method for Regulator Validation of Bagging Methods Used in Retail Banking

no code implementations5 Apr 2020 Jeremy Charlier, Vladimir Makarenkov

An ensemble method is a ML method that combines multiple hypotheses to form a single hypothesis used for prediction.

VecHGrad for Solving Accurately Complex Tensor Decomposition

no code implementations24 May 2019 Jeremy Charlier, Vladimir Makarenkov

Our experiments on five real-world data sets with the state-of-the-art deep learning gradient optimization models show that VecHGrad is capable of converging considerably faster because of its superior theoretical convergence rate per step.

A-Ward_p\b{eta}: Effective hierarchical clustering using the Minkowski metric and a fast k -means initialisation

no code implementations3 Nov 2016 Renato Cordeiro de Amorim, Vladimir Makarenkov, Boris Mirkin

This allows the cluster merging process to start from this partition rather than from a trivial partition composed solely of singletons.
