%description
Constructs sparse adjacency matrices from spatial coordinates, feature
measurements, class labels, and temporal indices. Supports
nearest-neighbor graphs, heat-kernel weights, graph Laplacians, diffusion
operators, and bilateral smoothers for graph-based data analysis,
following spectral graph methods in von Luxburg (2007)
<doi:10.1007/s11222-007-9033-z>, diffusion maps in Coifman and Lafon
(2006) <doi:10.1016/j.acha.2006.04.006>, and bilateral filtering in Tomasi
and Manduchi (1998) <doi:10.1109/ICCV.1998.710815>.
