An information processing device includes a first learning unit, a first error modeling unit, a first error generation unit, and a first estimation unit. The first learning unit learns a first estimation formula for estimating a first target variable of content on the basis of the feature quantity of the content. The first error modeling unit determines a first model of an error generated in the estimation of the first target variable based on the first estimation formula learned by the first learning unit. The first error generation unit generates, with the use of a random number, an error according to the first model determined by the first error modeling unit. The first estimation unit estimates the first target variable of the content by using the first estimation formula learned by the first learning unit and the random number generated by the first error generation unit.
