1. An internal combustion engine control device comprising a neural network model that receives three or more variables including at least a rotation speed, a load, and another specific variable of an internal combustion engine as inputs and outputs a control amount of the internal combustion engine,
wherein the neural network model includes a first neural network model having a reference value of the specific variable as an input and a second neural network model having a current value of the specific variable as an input, and
a reference value of the control amount calculated based on the rotation speed and the load is corrected using a difference or a ratio between the output of the first neural network model and the output of the second neural network model as a correction amount.
