ImageBind をもちいて算出し，これを分類器の入力として学生のエンゲージメントを推定する．大学生を対象とした模擬授業実験のデータを用いて評価した結果，提案手法は 2 値分類において 78.1% の精度を達成した．さらに，各マイクロ行動がエンゲージメント推定に与える影響度を SHAP 値により解析した結果，「メモを取る」「マウスを動かす」「キーボードを打つ」などのマイクロ行動が高エンゲージメントと関連することが明らかになった．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告モバイルコンピューティングと新社会システム（MBL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-05-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"53","bibliographicVolumeNumber":"2024-MBL-111"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":233974,"updated":"2025-01-19T09:55:10.826947+00:00","links":{}}
