Optimization apparatus, optimization method, and program

Abstract

A technology for simulating physiological activity more appropriately is provided. An optimization apparatus according to an embodiment includes an estimation unit, a first calculation unit, a second calculation unit, and an updating unit. The estimation unit estimates a physiological parameter indicating a physiological state using an estimation model. The first calculation unit calculates a first difference value based on a first estimated value of the physiological parameter in a first time interval and an actually measured value of the physiological parameter in the first time interval. The second calculation unit calculates a second difference value based on the first estimated value and a second estimated value of the physiological parameter in a second time interval previous to the first time interval. The updating unit adjusts the estimation model based on the first difference value and the second difference value.
