Supervised Feature Selection With a Stratified Feature Weighting Method

open access: yesIEEE Access, 2018
Feature selection has been a powerful tool to handle high-dimensional data. Most of these methods are biased toward the highest rank features which may be highly correlated with each other.

Feature Importance in Gradient Boosting Trees with Cross-Validation Feature Selection

open access: yesEntropy, 2022
Gradient Boosting Machines (GBM) are among the go-to algorithms on tabular data, which produce state-of-the-art results in many prediction tasks. Despite its popularity, the GBM framework suffers from a fundamental flaw in its base learners. Specifically,

Online Feature Selection for Visual Tracking [PDF]

open access: yes, 2016
Object tracking is one of the most important tasks in many applications of computer vision. Many tracking methods use a fixed set of features ignoring that appearance of a target object may change drastically due to intrinsic and extrinsic factors.

Neighborhood Ranking-Based Feature Selection

open access: yesIEEE Access
This article aims to integrate ${k}$ -NN regression, false-nearest neighborhood (FNN), and trustworthiness and continuity (T&C) neighborhood-based measures into an efficient and robust feature selection method to support the identification of ...

Analysis and Evaluation of Feature Selection and Feature Extraction Methods

open access: yesInternational Journal of Computational Intelligence Systems, 2023
Hand gestures are widely used in human-to-human and human-to-machine communication. Therefore, hand gesture recognition is a topic of great interest. Hand gesture recognition is closely related to pattern recognition, where overfitting can occur when ...

High-Dimensional Feature Selection by Feature-Wise Kernelized Lasso

open access: yes, 2019
The goal of supervised feature selection is to find a subset of input features that are responsible for predicting output values. The least absolute shrinkage and selection operator (Lasso) allows computationally efficient feature selection based on ...
