Therefore, we introduce a method for quantifying the risk of conceding a goal (Pitch Risk) and propose a model to output the modification of positioning in a phase based on the method. The model is intended for use by amateur athletes in their post-game review. Pitch Risk is calculated based on a fundamental rule of probability using Pitch Control, which indicates pitch dominance, xG, which indicates the probability of a goal, and SxA, which indicates the probability of an assist. Pitch Risk is a better representation of the risk of conceding a goal since the JS-divergence with the areas where the seven experienced soccer players reported a higher risk of conceding a goal in the phase is 0.14 for Pitch Risk compared to 118.18 for Pitch Control. We use GA for the Positioning Modification model. A total of 22 variables of distance and direction for the 11 defending players were used as chromosomes, and Pitch Risk was used as the evaluation function. Improvement of about 3% occurred when compared to the best of randomly generated. In addition, there was a player-linked improvement due to the simultaneous learning of 11 players. We believe that the improvement of accuracy for the model provides positioning interpretations to a wider number of people.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.20729/00231726","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.20729/00231726","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c)2024 Information Processing Society of Japan.本著作物の著作権は情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00116647","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-7764","subitem_source_identifier_type":"EISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"神宮司, 祐哉","creatorNameLang":"ja"},{"creatorName":"Jingushi, Yuya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"清, 雄一","creatorNameLang":"ja"},{"creatorName":"Sei, Yuichi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"田原, 康之","creatorNameLang":"ja"},{"creatorName":"Tahara, Yasuyuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"大須賀, 昭彦","creatorNameLang":"ja"},{"creatorName":"Ohsuga, Akihiko","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-03-14"}],"filename":"4.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","url":{"url":"https://uec.repo.nii.ac.jp/record/2000110/files/4.pdf"},"version_id":"b8ae616d-7f66-4ca0-81ea-5aabaf221d59"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"サッカー","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ポジショニング","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Pitch Control","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"遺伝的アルゴリズム","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"サッカーにおけるポジショニングの修正を行う遺伝的アルゴリズムモデルの提案","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"サッカーにおけるポジショニングの修正を行う遺伝的アルゴリズムモデルの提案","subitem_title_language":"ja"},{"subitem_title":"Proposal of Model for Modifying Positioning of Football by Genetic Algorithm","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"13","path":["6"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-03-14"},"publish_date":"2024-03-14","publish_status":"0","recid":"2000110","relation_version_is_last":true,"title":["サッカーにおけるポジショニングの修正を行う遺伝的アルゴリズムモデルの提案"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2024-03-14T07:22:12.819070+00:00"}
