mahjong players use the information they can see to make some inferences about the information they cannot see, such as the opponent's hand or deck of tiles. However, the mahjong agents studied so far do not explicitly estimate such incomplete information. Moreover, they do not use architectures that can maintain information about the history of the opponent's actions, which is necessary for an accurate estimation of such information. In this study, we use Transformer, a model that can represent and process mahjong board information and estimate the opponent's hand in an autoregressive manner. As a result, we were able to achieve higher accuracy than the method that estimates the hand by randomly selecting tiles that are not visible to the player.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"158","bibliographic_titles":[{"bibliographic_title":"ゲームプログラミングワークショップ2022論文集"}],"bibliographicPageStart":"151","bibliographicIssueDates":{"bibliographicIssueDate":"2022-11-04","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2022"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":222007,"updated":"2025-01-19T13:54:54.227940+00:00","links":{},"created":"2025-01-19T01:21:59.244924+00:00"}
