a large, online stream of multiple co-evolving data sequences (e.g., sensor/web activities streams), which contains multiple distinct time-series patterns based on inherent dynamics, how do we capture important patterns and forecast future values? In this paper, we present ModeCast, an efficient and effective method for forecasting co-evolving data sequences. ModeCastexploits Dynamic Mode Decomposition (DMD) to capture time-series patterns based on inherent dynamics. Our proposed method has the following properties: (a) Effective: it captures important time-evolving patterns in data streams and enables real-time, long-range forecasting; (b) General: our model can be practically applied to various types of time-evolving data streams; (c) Scalable: our algorithm does not depend on the length of data streams and thus is applicable to very large sequences. Extensive experiments on a real dataset demonstrate that ModeCastmakes long-range forecasts and consistently outperforms the best existing methods as regards accuracy, and the computational speed is sufficiently fast.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"11","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-04-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"17"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":233825,"updated":"2025-01-19T09:58:16.275397+00:00","links":{},"created":"2025-01-19T01:35:25.670544+00:00"}
