The termfeature selectionis used in machine learning for the process of selecting a subset of features (dimensions) used to represent the data (seeFeature Selection, andDimensionality Reduction). Feature selection can be seen as a part of data pre-processing potentially followed or coupled with fea...

Robustness or stability of feature selection techniques is a topic of recent interest, and is an important issue when selected feature subsets are subsequently analysed by domain experts to gain more insight into the problem modelled. In this work, we in
Feature Selection using Stochastic Gates (STG) is a method for feature selection in neural network estimation problems. The new procedure is based on probabilistic relaxation of the l0 norm of features, or the count of the number of selected features. The proposed framework simultaneously learns ei...
(Ridge), were compared with RIFS in this study. So this study investigated both the classification performances and the numbers of features for these feature selection algorithms. Two of the algorithms, Trank and Wrank, are from the Python scipy package, and all the other algorithms are from ...
Feature selection is demanded in many modern scientific research problems that use high-dimensional data. A typical example is to identify gene signatures that are related to a certain disease from high-dimensional gene expression data. The expression of genes may have grouping structures, for example...
