The dynamics is a global fluctuation arise from dynamic indications, and the articulation is a local fluctuation arise from expression marks. In this paper, the dynamics and the articulation are modeled by random walk and auto-regressive (AR) model, respectively. These models are embodied by using a switching linear dynamical system (SLDS), and an amplitude contour is decomposed by the SLDS. In our experiments, the proposed method successfully decomposed amplitude contours into dynamics and amplitude contours.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-02-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"17","bibliographicVolumeNumber":"2014-MUS-102"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":98457,"updated":"2025-01-21T12:27:15.818195+00:00","links":{},"created":"2025-01-18T23:44:42.524026+00:00"}
