In order to improve household finances, it is important to understand one's own lifestyle. For example, by understanding that one uses convenience stores frequently, one could partially switch to using supermarkets in order to reduce one's household expenditures. In this study, we attempt to predict the user's lifestyle from household account book data using a topic model. In the future, we expect to apply the result of this study to provide appropriate information and suggest ways to improve user's household finances depending on each user's lifestyle.
