MACHINE LEARNING DATA GENERATION DEVICE, MACHINE LEARNING DEVICE, WORK SYSTEM, COMPUTER PROGRAM, MACHINE LEARNING DATA GENERATION METHOD, AND METHOD FOR MANUFACTURING WORK MACHINE

Provided is a machine learning data generation device (1) including: a virtual sensor input generator (102) configured to generate a virtual sensor input, which is obtained by virtually generating a sensor input obtained as a result of performing sensing, by a sensor of a work machine (4), on a plurality of randomly piled subjects to be subjected to physical work by an operating machine (403) of the work machine (4), based on virtual subject models, which are virtual models of the plurality of randomly piled subjects; a virtual operation command generator configured to generate a virtual operation command, which is obtained by virtually generating an operation command for the operating machine of the work machine (4), depending on at least one of the virtual subject models or the virtual sensor input; a virtual operation outcome evaluator (116) configured to evaluate an outcome of the physical work performed by the operating machine (403) of the work machine in response to the virtual operation command in a virtual space; and a machine learning data generator (106) configured to generate machine learning data based on the virtual sensor input, the virtual operation command, and the evaluation of the virtual operation outcome evaluator.
