We show that the proposed\r\nmodification improves the performance of ordinary boosting methods. We\r\nalso review another problem in high-dimensional data.　Sparser solutions are\r\ndesirable from the view point of simple classification modeling and ease of\r\ninterpretation however there is no unique sparse solution in any single classifi-\r\ncation problem.　The possible combination of gene sets out of millions of gene\r\nexpression data is huge.　We show the existence of multiple optimum gene sets\r\nand consider the possible solutions.","subitem_description_type":"Other"}]},"item_1_description_18":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_description_7":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"総研大甲第1383号","subitem_description_type":"Other"}]},"item_1_select_14":{"attribute_name":"所蔵","attribute_value_mlt":[{"subitem_select_item":"有"}]},"item_1_select_8":{"attribute_name":"研究科","attribute_value_mlt":[{"subitem_select_item":"複合科学研究科"}]},"item_1_select_9":{"attribute_name":"専攻","attribute_value_mlt":[{"subitem_select_item":"15 統計科学専攻"}]},"item_1_text_10":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_text_value":"2010"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"PRITCHARD, Mari","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲1383_要旨.pdf","filesize":[{"value":"169.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"要旨・審査要旨","url":"https://ir.soken.ac.jp/record/2169/files/甲1383_要旨.pdf"},"version_id":"936c5b74-71fe-468d-b353-4c8733813561"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲1383_本文.pdf","filesize":[{"value":"996.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文","url":"https://ir.soken.ac.jp/record/2169/files/甲1383_本文.pdf"},"version_id":"55045d04-4e2a-48d9-b5cd-3b30891727f4"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Boosting method via the sparse learner approach for high-dimensional gene expression data","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Boosting method via the sparse learner approach for high-dimensional gene expression data"},{"subitem_title":"Boosting method via the sparse learner approach for high-dimensional gene expression data","subitem_title_language":"en"}]},"item_type_id":"1","owner":"21","path":["17"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-06-03"},"publish_date":"2011-06-03","publish_status":"0","recid":"2169","relation_version_is_last":true,"title":["Boosting method via the sparse learner approach for high-dimensional gene expression data"],"weko_creator_id":"21","weko_shared_id":-1},"updated":"2023-06-20T15:55:05.340644+00:00"}
