The algorithm works by choosing a weighted graph on the samples from a natural one-parameter family of graphs using an error based on the heat operator on the graphs. The estimated connected components of $X$ are identified as the support of the eigenfunctions of the heat operator with eigenvalue $1$, which allows the algorithm to work without requiring the number of expected clusters as input.", "revisions": [ { "version": "v1", "updated": "2015-06-08T19:39:37.000Z" } ], "analyses": { "keywords": [ "topological approach", "spectral clustering", "heat operator", "connected components", "uniform distribution" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable" } } }
