Abstract: An information processing device acts as a neural network based on time-series data. The information processing device includes a memory and a processor. The memory stores an input variable having an ordinal number in the time-series data, and a parameter group for the neural network. The processor calculates an intermediate variable for each ordinal number based on the input variable having the ordinal number by performing transformation based on the parameter group, and calculates an output variable having the ordinal number based on the calculated intermediate variable. Upon calculating an (n+1)-th intermediate variable, the processor performs weighted sum of a calculation result of an n-th intermediate variable and a transformation result in which the n-th intermediate variable and an (n+1)-th input variable are transformed based on the parameter group, to calculate the (n+1)-th intermediate variable.
