We considered model selection under regularization and shrinkage methods. In a sparse modeling, we derived a scaling method for LASSO, in which a bias problem is relaxed. And, we derived a risk-based model selection criterion for the estimate under the proposed method. We confirm its effectiveness through numerical experiments. Additionally, by introducing a scaling method, we derived a unified modeling method under a non-parametric orthogonal regression problem and we analyzed the generalization properties of the proposed method. On the other hand, in layered neural nets, we found that a deep structure affects over-fitting to noise.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2018年度～2020年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"18K11433","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"萩原, 克幸","creatorNameLang":"ja"},{"creatorName":"ハギワラ, カツユキ","creatorNameLang":"ja-Kana"},{"creatorName":"Hagiwara, Katsuyuki","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-11-22"}],"displaytype":"detail","filename":"2022RP0011.pdf","filesize":[{"value":"86.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2022RP0011","url":"https://mie-u.repo.nii.ac.jp/record/15252/files/2022RP0011.pdf"},"version_id":"79ffd540-d478-4e95-99ab-e5e35fe725a0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"スペース学習","subitem_subject_scheme":"Other"},{"subitem_subject":"階層型ニューラルネット","subitem_subject_scheme":"Other"},{"subitem_subject":"モデル選択","subitem_subject_scheme":"Other"},{"subitem_subject":"正則化","subitem_subject_scheme":"Other"},{"subitem_subject":"縮小推定","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"縮小推定を導入した貪欲法の下でのモデル選択規準についての研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"縮小推定を導入した貪欲法の下でのモデル選択規準についての研究","subitem_title_language":"ja"},{"subitem_title":"On model selection criteria under shrinkage estimation in greedy learning ","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1692661661745"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-11-22"},"publish_date":"2022-11-22","publish_status":"0","recid":"15252","relation_version_is_last":true,"title":["縮小推定を導入した貪欲法の下でのモデル選択規準についての研究"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-11-02T01:08:08.429616+00:00"}
