Abstract: To improve learning accuracy, while avoiding transferring of a dataset from an edge terminal to a cloud server. A management device accessible to a target object to be managed has a processor executing a program, a storage device storing the program, and a communication interface communicable with the target object. The processor executes a reception process for receiving first environmental information representing a first environment of the target object, a first generation process for generating relevant information representing relevancy between the first environmental information and second environmental information representing a second environment of the target object, a second generation process for generating a first learned model for inference by the target object in the first environment based on the relevant information and a second learned model for inference by the target object in the second environment, and a transmission process for transmitting the first learned model to the target object.

Abstract: Provided is a data processing system which links a plurality of types of processing each of which configured to implement a function. The data processing system includes: a gateway for inputting data; and a server for inputting data output from the gateway. The gateway applies first processing including one or more types of processing to the input data in accordance with information included in first flow information and outputs the processed data to the server. The server applies second processing to the data input from the gateway in accordance with the information included in the first flow information and thereafter applies third processing including one or more types of processing, specifies the second processing, generates, from the first flow information, second flow information including information for applying the third processing to the data input by the server from the gateway, and generates, from the first flow information, the second flow information including information for applying the first processing to the data input by the gateway and thereafter applying the second processing.

Abstract: A gateway suppresses data volume considering processing load information of a destination to reduce communication traffic volume of a network without suppressing the information with high severity. In a network system comprising the data center, the management node and the gateway connected via a plurality of networks, a communication function section of the gateway includes a table control unit that receives the processing load information of the data center as a packet destination from the management node and retains the information in a transfer management table. A transfer stop control unit of the gateway judges whether or not transfer of the packet is suppressed using the processing load information retained in the transfer management table, and suppresses the transfer of the predetermined packet upon judgment to suppress the packet transfer.
