WebJul 18, 2024 · We provide a randomized linear time approximation scheme for a generic problem about clustering of binary vectors subject to additional constrains. The new constrained clustering problem encompasses a number of problems and by solving it, we obtain the first linear time-approximation schemes for a number of well-studied … WebLow-rank matrix approximations are essential tools in the application of kernel methods to large-scale learning problems.. Kernel methods (for instance, support vector machines or Gaussian processes) project data points into a high-dimensional or infinite-dimensional feature space and find the optimal splitting hyperplane. In the kernel method the data is … WebIn this paper, we propose a novel PML method, namely Partial Multi-label Learning with Low-rank Constraint and Decomposition (PML-lcd). Specifically, we not only compute the low-rank approximation of the candidate label matrix, but also decompose the approximation into a low-rank ground-truth confidence matrix and a noisy matrix, i.e., … cricket counseling services
