1. A state determination device that determines an operation state of an injection molding machine, the state determination device comprising a processor configured to:
acquire data related to the injection molding machine;
perform numeric conversion for extracting a feature in a temporal direction or an amplitude direction, with respect to time-series data of physical quantity included in the data related to the injection molding machine based on reference time-series data which is time-series data in a reference step; and
perform machine learning using the data obtained through the performing of the numeric conversion, and generate a learning model,
wherein the state determination device further comprises a non-transitory memory, the non-transitory memory is configured to store a conversion table in which a content of numeric conversion for each data type of the time-series data is defined, and
the processor is configured to refer to the non-transitory memory so as to determine the content of numeric conversion performed for each data type of the time-series data.
