Title:
STATE PREDICTION DEVICE AND STATE PREDICTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/162778
Kind Code:
A1
Abstract:
This state prediction device for a target system: divides the processing steps of the target system into a plurality of blocks from an upstream step to a downstream step; generates teacher data for each block, including input data and output data for each block, from raw data obtained by observing the input data input to each block and the output data output from a given block; performs machine learning on local models included in cells that are allocated one-by-one to the respective blocks, by applying the teacher data for a given block to each local model; constructs a prediction model for the target system by connecting the plurality of cells after the machine learning, in a cascade from the upstream step to the downstream step; and calculates a predicted value for the output data output from the target system when the input data to the target system is input to the prediction model.
