(バイオロガー) によって今まで人が利用できなかった情報を利用することが可能になる．しかし，電力消費などのハードウェア制約や野生生物の行動頻度の偏りにより，出現頻度の低い行動をカメラでとらえることは依然として困難である．そこで本研究では，加速度センサなどの低コストセンサを用いて対象生物を常時観測し，出現頻度の低い行動が起こった時にのみ，カメラなどの高コストなセンサを起動することを試みる．教師なし学習技術を用いることで，研究者による予備知識や手動のアノテーションなしに希少行動を特定することが可能である．本手法の有効性を実証するために，オミズナギドリという海鳥を用いて実験を行った．実験の結果，加速度ベースの検出器と水圧ベースの検出器の両方から希少行動を観測することができ, 新たな生物学的な仮説を導くことができた．本手法は多様な野生生物種に適用が可能であり，生物学研究に新たな可能性を提供する．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告ユビキタスコンピューティングシステム（UBI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-05-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"15","bibliographicVolumeNumber":"2024-UBI-82"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":233862,"links":{}}
