Outline of Final Research Achievements

The purpose of this study is to analyze the data of patients’ background using machine learning method and to develop an application that could output helpful information. We also tried to construct a new system that will enable to continuously collect and utilize these data using tablet. We included data collection system of dental trauma.
Data collection system was completed. We will continue data collection using this system.
We tried to make decision tree from questionnaire of the mother class using application Weka (Machine Learning Group at the University of Waikato, New Zealand) . Several decision trees were generated, but we could not obtain proper decision trees according with the conventional theory. Since the contents of the sheet were slightly different at each clinic, missing values were likely to influence the analysis. A unified questionnaires style would be necessary. In addition, selection of the objective variable should be more important.
