high-dimensional data space, index structure for ε-neighbor search depends on a distance function which was used when the structure was constructed. To construct a “universal” index structure applicable to various distance functions, Yi et al. have already proposed a conversion rule which transforms L1 and L∞ distance into L2 distance and a framework of retrieval based on the conversion rule. In this paper, we propose a generalized conversion rule which transforms arbitrary Lp distance into Lv distance, and analyze the performance of retrieval of the proposed conversion rule by the volume of retrieval range using our method. We constructed index structures based on Lv distance for random data and music data. For each index structure, we execute ε-neighbor search by Lp distance using Lv distance conversion rule. From experiments, we confirmed that our method achieved ε-neighbor search by arbitrary Lp distance with only one index structure and that the results of experiments were similar to the analysis of performance of retrieval by the volume.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"105","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"93","bibliographicIssueDates":{"bibliographicIssueDate":"2005-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG8(TOD26)","bibliographicVolumeNumber":"46"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":17515,"updated":"2025-01-22T23:17:30.907275+00:00","links":{}}
