摘要

PROBLEM TO BE SOLVED: To provide a characteristic prediction device capable of reducing storage capacity for storing operation data so as to predict characteristics of a manufactured article processed by a processing device.;SOLUTION: The characteristic prediction device 1 includes an operation data-gathering unit 2, a characteristic value-gathering unit 3, a feature extracting unit 4, a storage unit 5, a characteristic predicting unit 6, and a learning unit 7. The storage unit 5 stores a feature quantity extracted by the feature extracting unit 4. The characteristic predicting unit 6 predicts, by using a prediction model 8, a characteristic value showing characteristics of the manufactured article, from the feature quantity stored by the storage unit 5, and outputs the predicted characteristic value as a characteristic predicted value. The learning unit 7 learns and updates the prediction model 8 so as to decrease an error between the characteristic predicted value and characteristic value.;COPYRIGHT: (C)2011,JPO&INPIT
