Abstract(in English) Reinforcement learning is a machine learning framework that an agent repeatedly observes reward from environment as a result of action to choose actions with high reward expectations. On the other hand, mobility models that satisfy the statistical properties of human mobility patterns have been proposed. However, a method of generating a mobility model based on reinforcement learning has not been sufficiently studied. In this paper, a dataset containing mobility traces of taxi cabs in San Francisco is used to propose a method of generating a mobility model that learns action selection by giving rewards, such as fare and gasoline charge, and also the distribution of passengers' positions. The $epsilon$-greedy method was used as the reinforcement learning algorithm. The degree of learning was compared by changing the search parameter $epsilon$. As a result, it was found that the cumulative reward was highest when $epsilon=0$ because the taxi movement included an implicit search. The generalization of the mobility model generation method using reinforcement algorithm was also considered.
