摘要： A state determination apparatus for determining a state related to an abnormality of an injection molding machine based on an operation state of the injection molding machine includes a machine learning apparatus for learning the state related to the abnormality of the injection molding machine. The machine learning apparatus observes, as a state variable that represents a current state of an environment, injection data that indicates the operation state of the injection molding machine, acquires label data that indicates the state related to the abnormality of the injection molding machine, and performs learning by associating the observed state variable with the acquired label data.
