pittsburgh

A dataset representing the graph structure of 402 census tracts of Allegheny County, PA.

datasets

Provides the standard operations for signal processing on graphs:
graph Fourier transform, spectral graph wavelet transform,
visualization tools. It also implements a data driven method
for graph signal denoising/regression, for details see
De Loynes, Navarro, Olivier (2019) <arxiv:1906.01882>.
The package also provides an interface to the SuiteSparse Matrix Collection,
<https://sparse.tamu.edu/>, a large and widely used set of sparse matrix
benchmarks collected from a wide range of applications.

pittsburgh function

A list with 4 elements:<ul>
<li><code>sA</code> A sparse matrix capturing the connections between spatially adjacent census tracts in Allegheny County.</li>
<li><code>xy</code> A matrix indicating the spatial location of each census tract.</li>
<li><code>f</code> Artificial signal with inhomogeneous smoothness across nodes and two sharp peaks near the center. This signal is formed using a mixture of five Gaussians in the underlying spatial coordinates.</li>
<li><code>y</code> Noisy version of the signal.</li>
</ul>
