Practical application to supervised learning problems of regression and classification type confirm that the resulting algorithms are competitive with state-of-the-art neural network-based methods.", "revisions": [ { "version": "v2", "updated": "2023-04-17T09:24:33.000Z" } ], "analyses": { "keywords": [ "function approximation", "associated fredholm integral equations", "state-of-the-art neural network-based methods", "classification type confirm", "approximate least-squares solution" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
