DEVICE AND METHOD FOR PROMPTING BEHAVIORAL CHANGE

摘要

A device for prompting behavioral changes generates a probability classification model in consideration of a probability dependence relation among nodes equivalent to each item (attribute) of health examination and doctor's question result data. The device tentatively changes an attribute value of each node of the classification model in an improvement direction, checks changes in classification class node upon tentatively changing, and generates higher-ranking N-pieces of improved plans as plan candidates in descending order of improvements of probabilities of the classification class nodes from the least improvement. The device generates an improved plan portfolio by listing the plan candidates in descending order of easiness of improvements. In response to changes in personal preference and restriction data, the device executes again the generation of the improved plan portfolio, and generates to present an improved plan portfolio after changing.
