| Abstract(in English) | In this paper, we propose a method which visualizes irregular multi-dimensional time-series data as a sequence of probabilistic prototypes, and apply it to medical data. Chronic hepatitis data, which represent typical medical test data, pose various challenges to conventional machine learning methods. We have proposed a method which obtains prototypes from the data, and the prototypes were admitted valid and comprehensive by physicians. This paper proposes PrototypeLines which represent a visualization method based on the prototyping method. PrototypeLines consider information criterion and hue recognition, and display medical data of each patient in a comprehensive format. Promising results were obtained by experiments in which we visualized patients based on their degrees of fibrosis. |
