Abstract: A computer generates a model for outputting an output value on the basis of a plurality of pieces of time-series data having different data types. The model includes a network that is for hied of connections of nodes having a recursive structure and updates states of the nodes according to a predetermined time step, and an adder that calculates the output value. The computer comprises: a learning unit configured to execute, for each of a plurality of output values, a learning process of calculating weight data including the plurality of weights by using learning data and a first storing unit configured to store a plurality of learning results each of which correlates a type of the output value and the weight data with each other.
