41. One of the cyclones has only a single known point in its track due to a sparsity of data. 42. Some of the parcels had to be doubled in size because of the sparsity of arable land within them. 43. The ideas of structured sparsity and feature selection can be extended to the nonparametric case of multiple kernel learning. 44. The sparsity of sayings recorded in the biblical accounts suggests that Jesus remained relatively silent for the hours he hung there. 45. At first glance, compressed sensing might seem to violate sparsity of the signal in question and not its highest frequency. 46. These algorithms are designed to exploit the sparsity of matrices that depend on the choices of variational formulation and discretization strategy. 47. Sparse dictionary learning is also doing the same thing, except for an additional constraints on the sparsity of the representation. 48. The graph colouring techniques explore sparsity patterns of the Hessian matrix and cheap Hessian vector products to obtain the entire matrix. 49. The listing for Soft Maple, P . Mathis and CCR were there because of references and sparsity of other sources. 50. Besides the norms discussed above, other norms used in structured sparsity methods include hierarchical norms and norms defined on grids.
