Server and oshibori management system

Abstract

A server according to one aspect includes a learning model storing unit, a receiving unit, an estimating unit, and a transmitting unit. The learning model storing unit stores a learning model learned by a neural network with an image for learning as an input value and the number of used oshiboris as an output value, the image for learning of the used oshiboris stored in a collection box photographed from above. The receiving unit receives an image for estimation photographed from above by a portable terminal. The estimating unit estimates the number of used oshiboris from the image for estimation received by the receiving unit, with the learning model stored in the learning model storing unit, by the neural network. The transmitting unit that transmits an estimation result estimated by the estimating unit toward the portable terminal.
