1. An estimation system comprising:
an acquisition circuit that acquires a captured image of an object to be estimated; and
an estimation circuit that uses a single learned model generated based on learning data, in which an image of the object to be estimated is associated with each of a plurality of attributes of the object to be estimated, to estimate a first attribute, included in the plurality of attributes, from a first output value of a first output layer corresponding to the first attribute and to estimate a second attribute, included in the plurality of attributes, from a second output value of a second output layer corresponding to the second attribute, with the captured image acquired by the acquisition circuit as an input image, wherein
the estimation circuit further estimates a candidate class based on the second output value calculated for each of a plurality of classes in which the second attribute is classified, and estimates the second attribute through linear interpolation using a plurality of candidate values included in the candidate class.
