Information processing apparatus, blood pressure estimation method, and storage medium

An information processing device is provided with: a biological information acquisition unit that acquires biological information of a person to be measured; a feature amount determination unit that determines a plurality of feature amounts on the basis of the biological information; a classification selection unit that selects a classification to which the person to be measured belongs from among a plurality of classifications according to a reference classification related to a first feature amount included in the plurality of feature amounts; and a blood pressure estimation unit that inputs a second feature quantity included in the plurality of feature quantities to a blood pressure estimation model selected according to the classification, and outputs an estimated blood pressure. 信息处理装置具备：生物体信息获取部，获取被测量者的生物体信息；特征量决定部，根据生物体信息决定多个特征量；分类选择部，从根据基准分类的多个分类中，选择被测量者所属的分类，该基准与多个特征量中包含的第一特征量相关；以及血压估计部，向根据分类选择的血压估计模型输入多个特征量中包含的第二特征量，输出估计血压。
