Adaptive Pass/Fail Judgment Using Dynamic Reference Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for pass/fail judgment of judgment targets, such as articles in appearance tests, suffer from reduced judgment accuracy due to environmental changes and the tradeoff between false-positives and false-negatives.
Innovation Solution
A judgment apparatus that uses monitoring data to perform pass/fail judgments by extracting characteristic amounts from image data and updating pass judgment characteristic information in real time based on the characteristic amounts of previously judged 'pass' targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pass judgment characteristic information is fixed based on initial data, then the judgment system is simple and stable, but judgment accuracy deteriorates due to environmental changes
Solution Approach 1:
The pass judgment characteristic information is transformed from a fixed static value to a dynamic value that automatically updates when new pass judgment results are obtained. The judgment system dynamically adapts by incorporating new characteristic amounts into the reference information, allowing it to evolve with environmental changes while maintaining operational simplicity
Solution Approach 2:
A feedback mechanism is implemented where the result of each pass/fail judgment is fed back to update the pass judgment characteristic information. When a pass judgment is made, the characteristic amount of that target is used to update the reference information, creating a closed-loop system that continuously improves accuracy based on actual performance data
2Reliability
If the pass judgment characteristic information is updated frequently, then judgment accuracy improves by adapting to environmental changes, but false-positives and false-negatives increase due to insufficient data
Solution Approach 1:
The system performs self-validation by automatically determining whether updated pass judgment characteristic information meets predetermined reliability criteria. The judgment system serves itself by evaluating the quality and sufficiency of its own data before accepting updates, preventing premature updates that would compromise judgment precision
Solution Approach 2:
Predetermined criteria are established in advance to validate whether updated characteristic information is sufficient before actually performing the update. This preliminary validation step ensures that only updates meeting quality standards are accepted, preventing false judgments caused by insufficient data

AI summary
To provide a judgment apparatus capable of achieving improved judgment accuracy, a judgment apparatus according to an embodiment judges a judgment target as pass or fail based on pass judgment characteristic information produced using characteristic amounts extracted from previously collected monitoring data items of judgment targets judged as pass. The pass/fail judgment processing includes extracting the characteristic amounts from monitoring data items of judgment targets sequentially input and successively performing pass/fail judgment of the judgment targets based on the pass judgment characteristic information. When one of the judgment targets is judged as pass in the successive pass/fail judgment, the characteristic amount of the judgment target judged as pass is used to update the pass judgment characteristic information. Pass/fail judgment of a judgment target subsequent to the judgment target judged as pass is performed based on the updated pass judgment characteristic information.
