In this case, the learning data set may be divided into n-dimensional input data consisting of shape information and molding conditions, and one-dimensional output data consisting of weight information of a product. n may mean the number of information included in the shape information and molding conditions. For example, if the shape information includes 15 pieces of information and the molding condition includes 5 pieces of information, n is 20.
