For the\ngiven nominal data, a rank in a form of complex number is assigned. The\nproposed method does not lose any information about the attribute and brings\nother properties previously unknown. The approach based on these knew\nproperties can been used for classification. The analyzed example shows that\nclassification with the use of coded nominal data or both numerical as well as\ncoded nominal data is more effective than the classification, which uses only\nnumerical data.","url_abs":"http://arxiv.org/abs/1601.01966v1","url_pdf":"http://arxiv.org/pdf/1601.01966v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"numerical-coding-of-nominal-data","repo_url":"https://github.com/IrisStark/ComplexEncoder","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"attribute","task_name":"Attribute"},{"task_slug":"classification-1","task_name":"Classification"},{"task_slug":"classification","task_name":"General Classification"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
