UFODMV: Unsupervised Feature Selection for Online Dynamic Multi-Views

open access: yesApplied Sciences, 2023
In most machine learning (ML) applications, data that arrive from heterogeneous views (i.e., multiple heterogeneous sources of data) are more likely to provide complementary information than does a single view.

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).

Unsupervised Cluster-Wise Hyperspectral Band Selection for Classification

open access: yesRemote Sensing, 2022
A hyperspectral image provides fine details about the scene under analysis, due to its multiple bands. However, the resulting high dimensionality in the feature space may render a classification task unreliable, mainly due to overfitting and the Hughes ...

Unsupervised Feature Selection on Data Streams [PDF]

open access: yesProceedings of the 24th ACM International on Conference on Information and Knowledge Management, 2015
Massive data streams are continuously being generated from sources such as social media, broadcast news, etc., and typically these datapoints lie in high-dimensional spaces (such as the vocabulary space of a language). Timely and accurate feature subset selection in these massive data streams has important applications in model interpretation ...
