Abstract

Example implementations described herein are directed to systems and methods for selecting appropriate data samples and features in an access and privacy restricted system. Example implementations involve selection of appropriate samples (e.g. patients) which have enough data sources bringing highly important factors based on the experienced risk factors at other facilities, which is stored as metadata. The risk factor management puts more prioritization on some patients which have more data in the required data source than the other patients among all data sample candidates. The similarity of the training data sample can be a criteria to select new sample sets. Further, the risk factor management selects valuable features effectively based on metadata derived from other facilities. Example implementations help improve machine learning accuracy as part of daily system management in a facility, and can be deployed across facilities without compromising access or privacy restrictions of the data.

Abstract

When the learning process is performed and the learning result is set in the wireless slave device, the time required for installing the wireless slave device is increased. Further, when data including the state of the inspection target object detected by the wireless slave device is transmitted as it is, the data size is increased, and the power consumption of the wireless slave device is also increased. A wireless slave device transmits a state of an inspection target object to a setting device as learning data, obtains, as an analysis result, a degree of difference between the state of the inspection target object and the normal state of the inspection target object based on a learning result set by the setting device, and wirelessly transmits data including the analysis result to the wireless master device. The setting device transfers the learning data received from the wireless slave device to the analysis management device and sets the learning result transmitted from the analysis management device in the wireless slave device. The analysis management device extracts a characteristic value characterizing the state of the inspection target object from the learning data transferred from the setting device and transmits the extracted characteristic value to the setting device as a learning result.

Abstract

The present invention provides a storage that enables all of a plurality of users to exercise snapshot management without causing a problem even in a situation where the plurality of users acquire snapshots of the same primary volume. The present invention provides a storage that enables all of a plurality of users to exercise snapshot management without causing a problem even in a situation where the plurality of users acquire snapshots of the same primary volume. Snapshots created through a plurality of interfaces are grouped. Grouping is performed at the time of snapshot creation. Snapshots in a group are required by other interfaces at a time when the snapshots are created. In a case where a deletion instruction is issued with respect to grouped snapshots, only the issuance of the deletion instruction is recorded without deleting snapshot data. In a case where the deletion instruction is issued with respect to all the snapshots in a group, the group is deleted because the snapshots in the group can be determined to be unnecessary for any user. After group deletion, snapshots instructed to be deleted and not grouped are deleted.

Abstract

A reference time point which is equivalent to a fault-prediction-execution time point is sequentially changed by setting, as a symptom sensing period, a period from a time point which is a predetermined first period-length before the reference time point until the reference time point, and by setting, as a prediction target period, a period from the reference time point until a time point which is a predetermined second period-length after the reference time point if a fault does not occur in the period from the reference time point until the time point which is the second period-length after the reference time point, and a period from the reference time point until a fault-occurrence time point if a fault occurs in the period from the reference time point until the time point which is the second period-length after the reference time point, and machine learning is performed by using, as an explanatory variable, a feature quantity based on the operation log information of the symptom sensing period, and using, as a response variable, a fault index value based on whether or not there is a particular-event occurrence in the operation log information corresponding to a fault occurrence in the fault record information of the prediction target period, and a period-length from the reference time point until the fault-occurrence time point.
