%description
In the era of big data and hyperconnectivity, learning high-dimensional
structures such as graphs from data has become a prominent task in machine
learning and has found applications in many fields such as finance, health
care, and networks. 'spectralGraphTopology' is an open source, documented,
and well-tested R package for learning graphs from data. It provides
implementations of state of the art algorithms such as Combinatorial Graph
Laplacian Learning (CGL), Spectral Graph Learning (SGL), Graph Estimation
based on Majorization-Minimization (GLE-MM), and Graph Estimation based on
Alternating Direction Method of Multipliers (GLE-ADMM). In addition, graph
learning has been widely employed for clustering, where specific
algorithms are available in the literature. To this end, we provide an
implementation of the Constrained Laplacian Rank (CLR) algorithm.
