In the real environment, SNR of the target sound against background noise is low, and there is a problem that it is necessary to catch the slight change in sound buried in noise. In this research, we propose a configuration in which a sound source extraction process by nonnegative matrix factorization (NMF) is provided at the preliminary stage of outlier detection process. We evaluated the improvement of the anomaly detection performance in the low SNR environment. In this experiment, SNR capable of detecting anomaly was greatly improved by providing NMF for pre-processing.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-06-09","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"33","bibliographicVolumeNumber":"2018-MUS-119"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":189900,"links":{}}
