  • Publication number: 20230288915
    Abstract: According to an embodiment, an information processing device includes one or more processors. The processors calculate a first degree of influence of a plurality of variables on output data, and a frequency at which the plurality of variables are selected as a variable influencing the output data, based on K first models. The K first models are models estimated using a plurality of pieces of input data including the plurality of variables. The plurality of input data are obtained in K periods. K is an integer of 2 or more. The first model receives input of the input data including the plurality of variables and outputs the output data. The processors output the first degree of influence and the frequency in association with each other.

  • Publication number: 20220083042
    Abstract: An information processing device includes a sufficiency determiner, a diagnostic unit, a request data generator, and a deliverer. The sufficiency determiner determines, concerning each diagnostic item in a target, whether plural pieces of inspection result data indicating inspection result by users, differing from a professional include sufficient pieces of effective inspection result data for diagnosing. The diagnostic unit diagnoses, concerning the diagnostic item, the condition of the target based on the plural inspection result data pieces when the plural inspection result data include sufficient pieces of inspection result data for diagnosing. The request data generator generates, concerning the diagnostic item, request data for requesting the users to conduct an inspection when the plural inspection result data pieces do not include sufficient pieces of inspection result data for diagnosing. The deliverer deliver the request data to user terminals.

  • Patent number: 11163853
    Abstract: According to one embodiment, a sensor design support apparatus includes: an inter-data feature calculator and a model constructor. The inter-data feature calculator combines any two pieces of data based on first to k-th data acquired from each of a plurality of sensors in response to first to k-th conditions being satisfied to generate a plurality of data pairs for each of sensors, the sensors monitoring a target; and calculates a plurality of inter-data features based on the plurality of data pairs. The model constructor calculates a plurality of coefficients corresponding to the plurality of inter-data features in a classification model based on state data indicating states of the monitoring target at times which the first to k-th conditions are satisfied, wherein the classification model associates the plurality of coefficients and the plurality of inter-data features with a value identifying a state of the monitoring target.
