(SFT-BERT) および各都市で固有の移動傾向を学習させたモデル (CMT-BERT) をエンコーダとして用い，下流モデルにより移動予測を行った．その結果，単一の都市の移動履歴のみで学習および予測を行った場合に対する優位性を示した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ヒューマンコンピュータインタラクション（HCI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-11-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"21","bibliographicVolumeNumber":"2024-HCI-210"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":240562,"updated":"2025-01-19T07:56:23.706673+00:00","links":{},"created":"2025-01-19T01:44:49.445522+00:00"}
