Refining Factors of Healthy Motivations with Observed Data

The paper proposes a method to estimate motivational factors for health promotion. To take healthy actions, we need motivations. Since motivational factors vary with individuals, approaches to improve our lifestyles depend on each person. The paper refines subjective estimation of motivational factors acquired with questionnaires with objective data observed from exercises users try for their health using a mathematical method, Non-negative Matrix Factorization. Through an experiment, we have confirmed the refinement enables us to estimate the strength of motivational factors of high objectivity. In addition, we have found recommended behaviors for each feature of motivational factors.
