Gene Selection in Cancer Classification Using Sparse Logistic Regression with L1/2 Regularization
In recent years, gene selection for cancer classification based on the expression of a small number of gene biomarkers has been the subject of much research in genetics and molecular biology.

Deep gene selection method to select genes from microarray datasets for cancer classification [PDF]
Microarray datasets consist of complex and high-dimensional samples and genes, and generally the number of samples is much smaller than the number of genes.

Hybrid gene selection approach using XGBoost and multi-objective genetic algorithm for cancer classification [PDF]
Microarray gene expression data are often accompanied by a large number of genes and a small number of samples. However, only a few of these genes are relevant to cancer, resulting in significant gene selection challenges.

A Modified Memetic Algorithm with an Application to Gene Selection in a Sheep Body Weight Study
Selecting the minimal best subset out of a huge number of factors for influencing the response is a fundamental and very challenging NP-hard problem because the presence of many redundant genes results in over-fitting easily while missing an important ...

Selective gene amplification [PDF]
We describe a system for directed evolution based on in vitro compartmentalisation in which amplification of a gene is coupled to the formation of product by the enzyme it encodes. This approach mimics the process of natural selection; 'fitter' genes--encoding more efficient enzymes--have more 'offspring'.

SLNL: A novel method for gene selection and phenotype classification
One of the central tasks of genome research is to predict phenotypes and discover some important gene biomarkers. However, there are three main problems in analyzing genomics data to predict phenotypes and gene marker selection. Such as large p and small
