A Stable Combinatorial Particle Swarm Optimization for Scalable Feature Selection in Gene Expression Data

24 Jan 2019Hassen DhrifLuis G. Sanchez GiraldoMiroslav KubatStefan Wuchty

Evolutionary computation (EC) algorithms, such as discrete and multi-objective versions of particle swarm optimization (PSO), have been applied to solve the Feature selection (FS) problem, tackling the combinatorial explosion of search spaces that are peppered with local minima. Furthermore, high-dimensional FS problems such as finding a small set of biomarkers to make a diagnostic call add an additional challenge as such methods ability to pick out the most important features must remain unchanged in decision spaces of increasing dimensions and presence of irrelevant features...
