Title:
教師データ生成装置および教師データ生成方法
Document Type and Number:
Japanese Patent JP6962868
Kind Code:
B2
Abstract:
To enable realization of highly accurate control from an early stage by starting plant control with artificial intelligence.SOLUTION: Based on plant operation actual performance data, an operation result evaluation value Tv, which is an evaluation value of a result of an operation performed during a period of a predetermined extraction time interval tband from a predetermined start time t1, is calculated. Using the operation result evaluation value Tv, whether new teacher data Tnew can be created or not is determined. When it is determined that teacher data T can be created, the teacher data T is extracted, which includes a teacher data input unit Tin calculated based on a quantity S(t) of plate shape state at the start time t1 and a teacher data output part Tout calculated based on a quantity O(t) of operation apparatus state during the period of the predetermined extraction time interval tband from the start time t1. The extracted teacher data T is stored in a database DB2 for teacher data for neural net learning.SELECTED DRAWING: Figure 1
