This paper introduces a novel model for spectral clustering to solve the problem of poor connectivity among points within the same cluster as this can negatively impact the performance of spectral clustering. The proposed method leverages both sparsity and connectivity properties ...

Spectral Clustering: Interpretation and Gaussian Parameter Spectral clustering consists in creating, from the spectral elements of a Gaussian affinity matrix, a low-dimensional space in which data are grouped into clusters. However, questions about the separability of clusters in the projection ... S ...

To this end, we applied a k-means clustering algorithm for all countries using the following variables: the mean latitude and longitude of the country border polygon, GDP, GDP per capita, population, country area and population. The algorithm grouped all countries into 20 clusters on the basis...

Increasing the number of environmental stressors could decrease ecosystem functioning in soils. Yet this relationship has not been globally assessed outside laboratory experiments. Here, using two independent global standardized field surveys, and a range of natural and human factors, we test the relati...
In addition, high-order spectral analysis can, technically, minimize the Gaussian noise. However, since the transformation of the bispectrum is not conducive to detection and identification, it generally absorbs a number of energies for two-dimensional picture recognition. The two-dimensional signal ...
