Computation of significance scores of unweighted Gene Set Enrichment Analyses

open access: yesBMC Bioinformatics, 2007
Background Gene Set Enrichment Analysis (GSEA) is a computational method for the statistical evaluation of sorted lists of genes or proteins. Originally GSEA was developed for interpreting microarray gene expression data, but it can be applied to any ...

A graph-based gene selection method for medical diagnosis problems using a many-objective PSO algorithm

open access: yesBMC Medical Informatics and Decision Making, 2021
Background Gene expression data play an important role in bioinformatics applications. Although there may be a large number of features in such data, they mainly tend to contain only a few samples.

Machine Learning and Integrative Analysis of Biomedical Big Data. [PDF]

open access: yes, 2019
Recent developments in high-throughput technologies have accelerated the accumulation of massive amounts of omics data from multiple sources: genome, epigenome, transcriptome, proteome, metabolome, etc. Traditionally, data from each source (e.g., genome)

The Performance Evaluation of The Random Forest Algorithm for A Gene Selection in Identifying Genes Associated with Resectable Pancreatic Cancer in Microarray Dataset: A Retrospective Study.

open access: yesCell journal, 2023
In microarray datasets, hundreds and thousands of genes are measured in a small number of samples, and sometimes due to problems that occur during the experiment, the expression value of some genes is recorded as missing. It is a difficult task to determine the genes that cause disease or cancer from a large number of genes.

Evaluation of variable selection methods for random forests and omics data sets

open access: yesBriefings Bioinform., 2017
Machine learning methods and in particular random forests are promising approaches for prediction based on high dimensional omics data sets. They provide variable importance measures to rank predictors according to their predictive power.

A novel hybrid algorithm based on Harris Hawks for tumor feature gene selection [PDF]

open access: yesPeerJ Computer Science, 2023
Background Gene expression data are often used to classify cancer genes. In such high-dimensional datasets, however, only a few feature genes are closely related to tumors.
