Feature selection is an important step in gene expression data analysis. However, many feature selection methods exist and a costly experimentation is usually needed to determine the most suitable one for a given problem. This paper presents the application of gradient boosting and neural network techniques for the construction of meta-models that can recommend rankings of {feature selection - classification} algorithm pairs for new gene expression classification problems through the usage of learning-to-rank and collaborative filtering approaches. Results in a corpus of 60 public datasets show the superiority of these techniques in producing more useful rankings in relation to classical meta-models
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
