In this day and age of dizzying changes in environment and values, updating wrong knowledge is as important as getting new knowledge. Therefore, I think that a methodology for updating knowledge is needed.<\/p>\n<p>As one example of it, I\u2019m researching automatic composition. If the system makes a \u201ccorrect\u201d piece of music based on an expert\u2019s theory, and the user doesn\u2019t like it, then the expert\u2019s theory is incomplete at least in that user\u2019s sense of value. In that case, that theory needs to be modified to fit the user\u2019s values. And it encourages the re-creation of existing theories.<\/p>\n<p>I\u2019ve worked on a variety of data science challenges in business. In that process, we often reset a goal because we realized the goal was not what we should be aiming for. Machine learning, the core technology of AI, is a mechanism to create a model which is optimized toward evaluation indicators from given data. Once the creation of models is automated, the human job will be to decide input data and metrics into the AI. I would like to present a methodology about it while conducting specific research.<\/p>\n<h2>Brief History<\/h2>\n<p class=\"fellow_brief\">Assistant Professor, Department of Data Science, Faculty of Data Science, Musashino University, Tokyo, Japan; Research Associate, GLOCOM, International University of Japan since 2018; current position since 2020.
