Researchers propose Fiedler number maximization for sparse graph learning from limited data

Researchers have developed a new method for learning sparse graphs from limited data, a problem often encountered when the number of observations is significantly less than the signal dimension. The approach incorporates the Fiedler number, a measure of graph connectedness, as a regularization term in the learning objective. This method includes a greedy algorithm for edge selection and a parallel variant using graph partitioning, which has shown improved robustness in sparse graph estimation compared to existing algorithms.

    Sparse Graph Learning from Sparse Data via Fiedler Number Maximization

    arXiv:2604.26132v1 Announce Type: cross Abstract: We aim to learn a sparse and connected graph from sparse data, where the number of observations K can be substantially smaller than the signal dimension N for signals x in R^N, and the underlying distribution is unknown. In this s…
