  • Publication number: 20210304070
    Abstract: A system for performing operation management of a machine learning model includes a task-inference ID association unit configured to, on the basis of a system data stream for outputting content of a task performed by a system that calls a machine learning model and a recorded data stream for inputting/outputting data when inference of the machine learning model is processed, calculate, with regard to association between the system data stream and the recorded data stream, the association between the system data stream and the recorded data stream from configuration information representing dependency between the system and the machine learning model.

  • Patent number: 11044319
    Abstract: An equipment analysis support apparatus includes an equipment constraint information storage unit that stores equipment constraint information which is a correspondence relationship between each process constituting work performed using a plurality of pieces of equipment and a constraint to be imposed on the equipment in each process; a work process information acquisition unit that acquires work process information which is information on a process of the work currently in progress; a configuration information generation unit that, when it is determined that a current work state is changed, specifies a constraint to be imposed on the equipment in the changed work state and generates a configuration of analysis processing of the equipment satisfying the specified constraint based on the acquired work process information and the equipment constraint information; and a processing execution unit that performs processing necessary for analysis of the equipment based on the generated configuration.

  • Publication number: 20210073676
    Abstract: The model improvement support system makes a determination, for each of one or more datasets selected by a model developer from among one or more datasets provided from an application developer and input to the model in utilization of the model, of whether or not the execution condition of the learning/evaluation program for performing learning/evaluation on the model satisfies an execution condition associated with the dataset, wherein the learning/evaluation is at least either of learning and evaluation of the model, and executes the learning/evaluation program with this dataset used as an input to the model if the result of the determination is affirmative.

  • Patent number: 10740214
    Abstract: Described is a means for switching a plurality of different data processing methods or means for changing the type of sensor data to be collected is required. A management computer includes a control unit which stores, in a memory, monitoring means for monitoring a plurality of operation processes to be monitored and management means connected to a network to manage management information about a plurality of different types of external devices for processing a plurality of types of sensor information via the network, the control unit executing the monitoring means and management means in a CPU, in which the control unit determines whether the plurality of operation processes to be monitored is changed, and instructs, when determining that the operation processes are changed, the plurality of different types of external devices to change the processing of the sensor information required to execute the operation processes before changing.
