Feature Selection MethodsFeature Selection AlgorithmsFeature selection is an important topic in data mining, especially for high dimensional datasets. Feature selection (also known as subset selection) is a process commonly used in machine learning, wherein subsets of the features available from the ...
The size of a dataset can be measUJ·ed in two dimensions, number of features (N) and number of instances (P). Both Nand P can be enormously large. This enormity may cause serious problems to many data mining systems. Feature selection is one of the long existing methods that deal ...
Nature-inspired algorithms (NIA) are proven to be the potential tool for solving intricate optimization problems and aid in the development of better computational techniques. In recent years, these algorithms have raised considerable interest to optimize feature selection problems. In literature, NIA is...
This study delves into a comparison between two feature selection methods: Shapley Additive exPlanation (SHAP)-value-based selection [3] and commonly used importance-based selection [4,5]. SHAP leverages game theory concepts to compute feature importance in two steps: training a classification model ...
In the context of high-dimensional credit card fraud data, researchers and practitioners commonly utilize feature selection techniques to enhance the performance of fraud detection models. This study presents a comparison in model performance using the m

Borutais a feature ranking and selection algorithm that was developed at the University of Warsaw. This algorithm is based on random forests, but can be used on XGBoost and different tree algorithms as well. At Fiverr, I used this algorithm with some improvements to XGBoost ranking and classifie...
Using the SNR-PPFS feature selection algorithms, we discovered a 38 gene signatures that performed well in distinguishing COAD tumors from normal samples. Bayesian network of the 38 genes revealed that DEGs with similar expression patterns or functions interacted more closely. We identified 14 up-...
In addition to feature pre-selection based on drug properties and biological relevance, we also evaluated automated feature selection algorithms in application to genome-wide expression data. We used two techniques, based on linear and non-linear methods. First, stability selection, which uses lasso ...
