WebMar 31, 2008 · This letter presents a semisupervised method based on kernel machines and graph theory for remote sensing image classification. The support vector machine (SVM) is regularized with the unnormalized graph Laplacian, thus leading to the Laplacian SVM (LapSVM). The method is tested in the challenging problems of urban monitoring and … Web机译:Dirichlet p-Laplacian特征值和Cheeger常数在对称图表上 获取原文 ... By the uniqueness of the first eigenfunction of p-Laplacian, as p -> 1, we identify the Cheeger constant of a symmetric graph with that of the quotient graph. By this approach, we calculate various Cheeger constants of spherically symmetric graphs. ...

WebCreated similarity matrix using gaussian distance function, computed unnormalized graph Laplacian and eigenvalues, applied k-means clustering to extract ROI, used morphology for post-processing. • Proved higher segmentation accuracy of spectral clustering on chronic wound images than simple k-means, contour based segmentation, histogram based ... Webbased approach using Laplacian Eigenmaps (LE) for story seg-mentation on broadcast news (BN) LVCSR transcripts [7]. LE is a geometrically motivated algorithm recently proposed for data representation [8]. We carry LE analysis on the sentence connective strength matrix and construct a Euclidean space in which each sentence is mapped to a vector. is sly cooper on steam

In this section, we study the normalized Laplacian Estrada index of edge-independent random graphs. Let T n ∈ R n × n be a diagonal matrix with its ( i , i ) -element given by ∑ j = 1 n p i j . Given a matrix M, denote its rank by rank ( M ) . We have the following result. is sly cooper on ps now
