Abstract: The learning apparatus according to one exemplary embodiment includes: a pattern extractor that extracts a time fluctuation pattern of an amplitude of a feature frequency from state observation signal data up to a first time point, the state observation signal data indicating an operation state of equipment, the feature frequency being associated with a part of the equipment; a training data generator that generates, based on the time fluctuation pattern of the amplitude of the feature frequency, simulated state observation signal data representing the time fluctuation pattern of the amplitude of the feature frequency at and after the first time point, and generates training data including the simulated state observation signal data; and a learner that generates a classification model for determination of a failure state of the part of the equipment using the training data.
