To estimate processes that a worker has performed, a sequence in which the worker has performed the processes, and a route in which the worker has moved to perform the processes.SOLUTION: A learning device comprises: a gathering part which gathers process operation information representing operation states of respective processes and reception level information including reception levels of signals that a first radio station receives from second radio stations installed for the respective processes; and a learning part which uses teacher data having the process operation information and the reception level information linked, process by process, so as to allow a generation model for estimating a state of movement of a third radio station to be learned.SELECTED DRAWING: Figure 1 【課題】作業者が行った工程、工程を行った順序および工程を行うために工程間を移動した経路を推定すること。【解決手段】本開示の一実施例に係る学習装置は、各工程の稼動状態を示す工程稼動情報と、第１の無線局が各工程それぞれに設置された第２の無線局から受信した信号の受信レベルを含む受信レベル情報と、を収集する収集部と、工程ごとに前記工程稼動情報と前記受信レベル情報とを紐付けた教師データを用いて、第３の無線局の移動の状態を推定するための生成モデルを学習させる学習部と、を備える。【選択図】図１
