Application: Processing method, processing system, and processing program (Patent ID: US20240095581A1)

The patent filed by Nippon Telegraph and Telephone Corp. describes a processing method executed by a system that performs inference in both an edge device and a server device. The method involves determining changes in the tendency of a target data group based on load variation or inference accuracy decrease in either device, and then executing relearning of the models used for inference if such changes are detected. The relearning process involves using data that has a significant impact on the load variation or inference accuracy decrease in the target data group.

Additionally, the patent includes claims for a processing system that implements the described method, processing circuitry for determining changes in the target data group's tendency, and a non-transitory computer-readable recording medium storing a processing program to execute the method. The system and program are designed to adapt the inference models based on the identified changes in the target data group, ensuring optimal performance and accuracy in the inference process.
