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 ...

A Supervised Feature Selection Method For Mixed-Type Data using Density-based Feature Clustering [PDF]

open access: yesarXiv, 2021
Feature selection methods are widely used to address the high computational overheads and curse of dimensionality in classifying high-dimensional data. Most conventional feature selection methods focus on handling homogeneous features, while real-world datasets usually have a mixture of continuous and discrete features.

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.

Online Feature Selection with Group Structure Analysis [PDF]

open access: yes, 2016
Online selection of dynamic features has attracted intensive interest in recent years. However, existing online feature selection methods evaluate features individually and ignore the underlying structure of feature stream. For instance, in image analysis, features are generated in groups which represent color, texture and other visual information ...

Deep Feature Selection Using a Novel Complementary Feature Mask [PDF]

open access: yesarXiv, 2022
Feature selection has drawn much attention over the last decades in machine learning because it can reduce data dimensionality while maintaining the original physical meaning of features, which enables better interpretability than feature extraction. However, most existing feature selection approaches, especially deep-learning-based, often focus on the

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 ...

Structure Preserving Non-negative Feature Self-Representation for Unsupervised Feature Selection

open access: yesIEEE Access, 2017
Inspired by the importance of self-representation and structure-preserving ability of features, in this paper, we propose a novel unsupervised feature selection algorithm named structure-preserving non-negative feature self-representation (SPNFSR).

Optimal Feature Aggregation and Combination for Two-Dimensional Ensemble Feature Selection

open access: yesInformation, 2020
Feature selection is a way of reducing the features of data such that, when the classification algorithm runs, it produces better accuracy. In general, conventional feature selection is quite unstable when faced with changing data characteristics.

Utilizing Semantic Textual Similarity for Clinical Survey Data Feature Selection [PDF]

open access: yesarXiv, 2023
Survey data can contain a high number of features while having a comparatively low quantity of examples. Machine learning models that attempt to predict outcomes from survey data under these conditions can overfit and result in poor generalizability. One remedy to this issue is feature selection, which attempts to select an optimal subset of features ...
