This algorithm builds upon the traditional k-means and\nspectral clustering frameworks by subdividing data into small Voronoï\nregions, which are subsequently merged according to a connectivity\nmeasure. Drawing inspiration from Support Vector Machine’s margin\nconcept, a non-parametric clustering approach is proposed, building an\naffinity margin between each pair of Voronoï regions. This approach\ndelineates intricate, non-convex cluster structures and is robust to\nhyperparameter choice. The numerical experiments underscore Spectral\nBridges as a fast, robust, and versatile tool for clustering tasks\nspanning diverse domains. Its efficacy extends to large-scale scenarios\nencompassing both real-world and synthetic datasets. The Spectral Bridge\nalgorithm is implemented both in Python\n(\u003chttps://pypi.org/project/spectral-bridges\u003e) and R\n\u003chttps://github.com/cambroise/spectral-bridges-Rpackage\u003e).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcomputorg%2Fpublished-202412-ambroise-spectral","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcomputorg%2Fpublished-202412-ambroise-spectral","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcomputorg%2Fpublished-202412-ambroise-spectral/lists"}
