Information processing apparatus, information processing method, and computer program

According to one embodiment, an information processing apparatus includes an estimator configured to estimate a state of an observation target on a first time, based on data on the first time included in time-series data obtained from the observation target. Also, an information processing method for estimating a state of an observation target on a first time, based on data on the first time included in time-series data obtained from the observation target is provided.

According to one embodiment, information processing device includes a storage and a processing circuit. The storage is configured to store configuration data of a plurality of devices and error history data including a plurality of entries each with a type of error. The processing circuit is configured to: extract the entries with a specific type of error which are positive examples; extract the remaining entries which are negative examples; select a part of the negative examples with each type of error; generate learning data based on the positive examples, the selected negative examples and the configuration data at a time when the specific type of error occurred; and generate a diagnosis model for estimation of possibility the specific type of error occurs by using the learning data.

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

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.

Sensor design support apparatus, sensor design support method and non-transitory computer readable medium
