つの課題が存在する．1 つ目は，生理指標の計測機器が高価であり，装着が簡便でない点である．2 つ目は，精度向上が期待できる，感情推定に不要な指標の削除が行われていない点である．そこで本研究では，これら 2 つの課題を解決しつつ，精度が良い感情推定モデルの構築を目的とする．安価かつ装着が簡便な単一電極の脳波計と光電式脈波計を用いた．また，多角的な複数手法により不要な指標の削除を行った．男性 18 名，女性 7 名の計 25 名の実験参加者から機械学習に用いるデータを収集した．そして，深層学習により感情推定モデルを構築し，そのモデルの精度検証には，推定を試みる対象人物の生理指標のデータを学習データに含める方法と学習データに含めない方法の 2 種類を用いた．その結果，前者では 4 感情分類において 99% の精度を得た．一方，後者では前者と比べ著しく低い 23% の精度を得た．これは学習をせず無作為な推定をするモデルの精度 25% を下回る結果である．この結果により，安価な機材でも感情推定をする対象人物の生理指標のデータを学習データに含めることができれば精度よく感情推定でき，目的が達成できることが示唆された．しかし，含めることができなければ低い感情推定精度となり，目的が達成できないことが示唆された．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ユビキタスコンピューティングシステム（UBI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-05-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2021-UBI-70"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
