PROBLEM TO BE SOLVED: To predict an onset based on a subject's activity pattern. An information processing apparatus includes an acquisition unit that acquires data regarding a first activity amount performed by a plurality of first subjects and a data regarding a second activity amount performed by a second subject, and an activity. A calculation unit that calculates a characteristic amount from data related to the amount, a generation unit that generates a disease onset prediction model based on the characteristic amount calculated from the data related to the first activity amount, and the disease onset prediction model And a prediction unit that outputs a disease onset prediction related to the second subject based on the feature amount calculated from the data related to the second activity amount. [Selection diagram] Figure 1【課題】被験者の活動量パターンに基づいて、発症予測を行うこと。【解決手段】情報処理装置は、複数の第1の被験者が行った第1の活動量に係るデータ及び第2の被験者が行った第2の活動量に係るデータを取得する取得部と、活動量に係るデータから特徴量を算出する算出部と、前記第1の活動量に係るデータから算出された前記特徴量に基づいて、疾病発症予測モデルを生成する生成部と、前記疾病発症予測モデル及び前記第2の活動量に係るデータから算出された前記特徴量に基づいて、前記第2の被験者に係る疾病発症予測を出力する予測部とを有する。【選択図】図1
