CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE, IN-VEHICLE ELECTRONIC CONTROL UNIT, MACHINE LEARNING SYSTEM, CONTROL METHOD OF INTERNAL COMBUSTION ENGINE, MANUFACTURING METHOD OF ELECTRONIC CONTROL UNIT, AND OUTPUT PARAMETER CALCULATION DEVICE

A control device of an internal combustion engine includes a parameter acquisition unit that acquires a plurality of input parameters, a calculation unit that calculates at least one output parameter using a neural network model, and a controller that controls the internal combustion engine. The neural network model includes a plurality of neural network units and an output layer. Each of the neural network units includes one input layer and at least one intermediate layer. The neural network model inputs different combinations of input parameters selected from the input parameters to each of the input layers of the neural network units such that a total number of input parameters to be input to the neural network units is larger than the number of the input parameters.
