An identification device including a generation unit and an information identification unit. The generation unit generates factor information relating to pulse-wave information with respect to an identification target in accordance with biological model information representing a relevance between pulse-wave information representing a pulse wave and the factor information representing a factor of pulse wave. The information identification unit selects certain list information satisfying a predetermined determination criterion of the factor information generated by the generation unit out of list information associating the factor information generated based on the pulse-wave information representing a pulse wave of a biological subject to be an identification target with identification information for identifying the biological subject, and identifies the identification information in the selected certain list information.

Identification device, identification method, and recording medium with recorded identification program

Provided are a prediction device and the like capable of more accurately simulating an analysis target. The prediction device generates function information for a gene sequence of a living body to be an analysis target based on first model information representing a relevance between sequence information and the function information, the sequence information representing the gene sequence of the analysis target, the function information representing a function potentially expressed by the gene sequence; and generates prediction information representing observation information predicted for the analysis target based on second model information and the function information, the second model information representing a relevance among the function information of the living body, environment information representing an environment around the living body, and the observation information observed for the living body, the function information being generated for the gene sequence of the analysis target.

Prediction device, gene estimation device, prediction method, and non-transitory recording medium

A plant monitoring apparatusincludes: a soil state estimation unitthat estimates a state of soil by, with use of frequency association information calculated based on vibration measured via the soil, referencing soil state estimation information in which the frequency association information and information indicating states of the soil are associated with soil states; and a plant state estimation unitthat estimates a state of a plant by, with use of growth association information that was calculated based on vibration of the plant and indicates growth of the plant, referencing plant state estimation information in which the growth association information and information indicating states of the plant above a plant soil surface are associated with plant states above the plant soil surface.

Plant monitoring apparatus, plant monitoring method, and computer-readable recording medium

A plant monitoring apparatusincludes: an extraction unitthat extracts a feature amount in a frequency response of vibration of a target plant with use of the vibration; a calculation unitthat calculates a change that indicates growth of the plant, based on the extracted feature amount and a reference feature amount that corresponds to a reference state of the plant; and an estimation unitthat estimates a state of the plant by, with use of the calculated change, referencing state information in which changes of the feature amount from the reference feature amount corresponding to growth of the plant are associated with states of the plant.

Provided is an information processing device, etc., that provides information which is the basis for quick detection of abnormalities that occur in a device. An information processing device calculates a degree of suitability between observation information and prediction information, the observation information observed for a system suffering an effect from an certain device, the prediction information predicted in accordance with a model for a state of the system; and calculates a difference between manipulation amount to the certain device and predictive manipulation amount predicted for the manipulation amount based on the model, the difference being a difference in case that the degree satisfies a predetermined calculation condition.

Information processing device, information processing method, and non-transitory recording medium

Provided are an abnormality determination device and the like that are able to accurately determine abnormalities regarding an inspection subject. The abnormality determination device is configured to calculate a scatter degree of differences between prediction information on an observation target and observation information on the observation target, the prediction information being an information generated in accordance with a scenario that represents an aspect of state change of the observation target, the observation information generated by an inspection target; and determine whether or not the inspection target is abnormal based on the calculated degree.
