Web11 iul. 2024 · Many feature extraction methods reduce the dimensionality of data based on the input graph matrix. The graph construction which reflects relationships among raw data points is crucial to the quality of resulting low-dimensional representations. To improve the quality of graph and make it more suitable for feature extraction tasks, we incorporate a … Web18 apr. 2024 · In light of this, this paper presents a joint multi-view unsupervised feature selection and graph learning (JMVFG) approach. Particularly, we formulate the multi …
Unsupervised feature selection with adaptive multiple …
WebTo solve this problem, a simple and efficient unsupervised model is proposed to perform feature selection. We formulate PCA as a reconstruction error minimization problem, and incorporate a -norm regularization term to make the projection matrix sparse. Web15 apr. 2024 · FDM is used to build the graph, as shown in Fig. 2, where features are used as nodes, and elements of FDM are the edges’ weight between nodes.The graph is denoted as G(F, E), where F represents the set of feature nodes and E is the set of edges between feature nodes.. 2.2 Feature Ranking with Eigenvector Centrality.
