The effect of incorporating noise covariance into inverse procedures was examined by computer simulations. The parametric projection filter, which allows inverse estimation with the presence of information on the noise covariance, was applied to an inhomogeneous three-concentric-sphere model under various noise conditions in order to estimate the cortical potentials from the scalp potentials. The present simulation results suggest that incorporation of information on the noise covariance allows better estimation of cortical potentials, than inverse solutions without knowledge about the noise covariance, when the correlation between the signal and noise is low. The method for determining the optimum regularization parameter, which can be applied for parametric inverse techniques, is also discusse.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110004069216","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 2003 IEICE"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10826272","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168532","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hori, Junichi"}],"nameIdentifiers":[{"nameIdentifier":"6365","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"He, Bin"}],"nameIdentifiers":[{"nameIdentifier":"6366","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"110004069216.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110004069216.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1951/files/110004069216.pdf"},"version_id":"d3b51f2a-0faf-4d68-aeec-5574eecf53c9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"high resolution EEG","subitem_subject_scheme":"Other"},{"subitem_subject":"cortical potential imaging","subitem_subject_scheme":"Other"},{"subitem_subject":"inverse problem","subitem_subject_scheme":"Other"},{"subitem_subject":"parametric projection filter","subitem_subject_scheme":"Other"},{"subitem_subject":"non-uniform noise","subitem_subject_scheme":"Other"},{"subitem_subject":"noise covariance","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":"EEG Cortical Potential Imaging of Brain Electrical Activity by means of Parametric Projection Filters(Biocybernetics, Neurocomputing)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"EEG Cortical Potential Imaging of Brain Electrical Activity by means of Parametric Projection Filters(Biocybernetics, Neurocomputing)"},{"subitem_title":"EEG Cortical Potential Imaging of Brain Electrical Activity by means of Parametric Projection Filters(Biocybernetics, Neurocomputing)","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-02-28"},"publish_date":"2014-02-28","publish_status":"0","recid":"1951","relation_version_is_last":true,"title":["EEG Cortical Potential Imaging of Brain Electrical Activity by means of Parametric Projection Filters(Biocybernetics, Neurocomputing)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:45.603729+00:00"}
