Because of the movement of reference Wi-Fi access points, we sometimes get a Wi-Fi position that has more than dozens of meters errors. In this paper, we detect and correct such errors automatically by comparing current Wi-Fi position with current positions predicted from a history of Wi-Fi positions. However, performances of the position predictors change greatly with the user's context (e.g. migration speed and density of access points around the user). So, we design context-aware frameworks for error detection and correction by employing an ensemble of predictors that have strengths and weakness for different contexts.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"388","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"378","bibliographicIssueDates":{"bibliographicIssueDate":"2014-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"55"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:44:38.422495+00:00","id":98372,"links":{}}
