We proposed a novel source separation technique that uses a tensor product expansion. This signal separation technique means that the background noise, which is observed in almost all input signals, can be estimated using a tensor product expansion (TPE) where the absolute error (AE) is used as the error function, which is thus known as TPE-AE. TPE-AE has two problems: the first is that the results of TPE-AE are strongly affected by Gaussian random noise, and the second is that the estimated signal varies widely because of the random search. To solve these problems, an outer product expansion based on a modified trimmed mean (MTM) is proposed in this paper. The results show that this novel technique separates the background noise from the signal more accurately than conventional methods.","subitem_description_type":"Other"}]},"item_10001_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{"name":"内匠, 逸"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Institute of Electronics, Information and Communication Engineers"}]},"item_10001_relation_34":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1587/transfun.E97.A.2114"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1587/transfun.E97.A.2114","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_35":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"130004706359"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/130004706359","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_37":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.ieice.org/jpn/books/transaction.html"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ieice.org/jpn/books/transaction.html","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168508","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_33":{"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":"Itai, Akitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yasukawa, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takumi, Ichi","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Hata, Masayasu","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":"2017-08-25"}],"displaytype":"detail","filename":"TakumiIchi_2014_P1.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","license_note":"copyright(C)2014 IEICE","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/6137/files/TakumiIchi_2014_P1.pdf"},"version_id":"5dc9b995-2160-471e-9bb9-08d058ea6fbb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"background noise reduction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tensor product expansion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electromagnetic wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"signal processing","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"The Background Noise Estimation in the ELF Electromagnetic Wave Data Using Outer Product Expansion with Non-linear Filter","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Background Noise Estimation in the ELF Electromagnetic Wave Data Using Outer Product Expansion with Non-linear Filter","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["31"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-08-25"},"publish_date":"2017-08-25","publish_status":"0","recid":"6137","relation_version_is_last":true,"title":["The Background Noise Estimation in the ELF Electromagnetic Wave Data Using Outer Product Expansion with Non-linear Filter"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T14:01:03.327565+00:00"}
