A feedback structure and its learning algorithm are proposed for overcomplete blind source separation (BSS). The number of sources is larger than that of the sensors. In the proposed method, the signal sources are separated in several groups. Among them, at least one output can separate a single signal source under some condition. The outputs of the unmixing block are evaluated, which output provides a single signal source. The separated single signal source is fed back to the input node, and subtracted from the input signal, in order to reduce the number of equivalent signal sources.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"理工研究域　電子情報学系","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEICE The Institute of Electronics, Information and Communication Engineers"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ieice.org/jpn/index.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110003298779","subitem_relation_type_select":"URI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10013221","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0913-5685","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"加藤, 治雄"},{"creatorName":"ナカヤマ, ケンジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中山, 謙二"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"平野, 晃宏"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-NAKAYAMA-K-43_m.pdf","filesize":[{"value":"8.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-NAKAYAMA-K-43_m.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/8130/files/TE-PR-NAKAYAMA-K-43_m.pdf"},"version_id":"bf5eda6f-9587-4842-8aee-0a673663c53e"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"オーバーコンプリート形ブラインド信号源分離の構成法と学習法(信号処理, 符号化とそれらを用いた知的マルチメディアシステム, 一般)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"オーバーコンプリート形ブラインド信号源分離の構成法と学習法(信号処理, 符号化とそれらを用いた知的マルチメディアシステム, 一般)"},{"subitem_title":"A Feedback Structure and Its Learning Algorithm for Overcomplete Blind Source Separation","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"8130","relation_version_is_last":true,"title":["オーバーコンプリート形ブラインド信号源分離の構成法と学習法(信号処理, 符号化とそれらを用いた知的マルチメディアシステム, 一般)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T02:13:51.024540+00:00"}
