These collected measurements are obtained from a sparse network of monitoring stations and are not always collected on a daily basis, leading to large amounts of missing data.
The resulting accurate reconstruction of the coloring of the sphere indicates that the topology and geometry of this cognitive map (whose semantic was in this case known by construction) could be reconstructed from a sparse subset of synonym and antonym relations.
To face this intrinsically difficult problem, we propose a novel generative model, where biclustering is approached from a sparse low-rank matrix factorization perspective.
Our method involves adapting a task-dependent LM that is created from a sparse amount of text using a large translated text, where denotes the machine translation of the rich corpus, preferably in the same domain area as the task.
Imaging spectroscopy, also known as hyperspectral imaging, has been transformed in less than 30 years from being a sparse research tool into a commodity product available to a broad user community.
He is from Niger, where sparse rains resulted in a modest crop harvest, leaving Saguiro's mother able to feed her children only one meal a day.
Compressed sensing (CS) [1 3] is to recover a sparse signal from the measurements that are believed to be incomplete.
Actually, since only L2 entries out of G2 can differ from zero, D is a sparse matrix.
where z is the image reconstructed from a sparse x-let coefficient vector, v is a positive constant depending on the statistical parameters of the signal model and on the noise variance (see Equation 14 below), and Φ* is the x-let frame used to impose sparsity.
Considering the terms in this matrix, then ZT Z is a sparse matrix, and from (4) we see that has some sparse structure, although is a dense matrix.
