The standard approaches (e.g. cross-validation) for kernel selection, used in two-class classification problems, can not be used directly due to the specific nature of a data (absence of a second, abnormal, class data). In this paper we generalize several kernel selection methods from binary-class case to the case of one-class classification and perform extensive comparison of these approaches using both synthetic and real-world data.", "revisions": [ { "version": "v1", "updated": "2017-07-12T21:03:36.000Z" } ], "analyses": { "keywords": [ "model selection", "kernel selection methods", "network intrusion detection", "two-class classification problems", "one-class classification algorithms" ], "tags": [ "conference paper", "journal article" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable" } } }
