Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Selection of a small subset of informative features from data is a basic technique in signal processing, machine learning, and statistics. Joint selection of entire groups of features is desirable if the data features exhibit shared grouping structures. Bilevel feature selection constitutes a refinement of these ideas, producing a small subset of data features that themselves belong to a small number of feature groups. Hover, algorithms for bilevel feature selection suffer a computational cost that can be cubic in the size of the data, hence impeding their utility. ,  propose an approach for bilevel feature selection that resolves this computational challenge. The core component of our approach is a novel fast algorithm for bilevel hard thresholding for a specific non-convex, discrete optimization problem. Our algorithm produces an approximate solution to this problem, but only incurs a nearly-linear running time.  extend this algorithm into a two-stage thresholding method that performs statistically as ll as the best available methods for bilevel feature selection, but that also scales extremely ll to massive dataset sizes.
