Automatic text segmentation, which is the task of breaking a text into topically-consistent segments, is a fundamental problem in Natural Language Processing, Document Classification and Informationâ€¦ (More)

We use the spectra of Dirac type operators on the sphere S to produce sharp L inequalities on the sphere. These operators include the Dirac operator on S, the conformal Laplacian and Paenitzâ€¦ (More)

Natural images in the colour space Y UV have been observed to have a non-Gaussian, heavy tailed distribution (called â€˜sparseâ€™) when the filter is applied to the chromacity channel U (and equivalentlyâ€¦ (More)
