ESTIMATION DEVICE, ESTIMATION METHOD, AND PROGRAM

Provided is an estimation device configured to: acquire prediction parameters, which are distribution information on second parameters, by inputting actual parameters, which are first parameters, into: a first trained model, which is trained to output distribution information on second parameters in response to input of first parameters by using training data and correct data; and a second trained model, which is trained to output distribution information on second parameters in response to input of first parameters by using training data and correct data; and estimate whether or not the second mobile object is to take the predetermined action by comparing the prediction parameters with the actual parameters at a subject time of the prediction parameters.
