Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If machine learning-based model training is conducted using training data including extra data to be detected with anomalies, then detection anomalies such as false positives and false negatives can be reduced, but it becomes difficult to determine whether the training limit has been reached

Engineering Contradiction:
Improvedetection accuracyVSAvoidtraining status information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system implements feedback by comparing prediction results across multiple training iterations. The determination unit analyzes whether errors and omissions in prediction results have stabilized by comparing current training results with previous training results, providing feedback on whether further training will yield improvements or if the training limit has been reached.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary evaluation mechanism that uses reference information and comparison processes to assess training status. The determination unit acts as an intermediary between the training process and the trainer, objectively evaluating whether the training limit has been reached based on stabilization of prediction errors across iterations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple training iterations are performed to eliminate detection anomalies, then detection precision improves, but training time and computational resources increase

Engineering Contradiction:
Improveobject detection precisionVSAvoidtraining time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs training iterations beyond what might be considered sufficient, continuing until the stabilization criterion is met. This partial/excessive action ensures that the training limit is definitively identified, preventing both premature termination and unnecessary extended training, thus optimizing the balance between precision improvement and time consumption.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The feedback mechanism compares prediction results across training iterations to detect stabilization. When errors and omissions stop improving between iterations, the system automatically determines that the training limit has been reached, providing an objective stopping criterion that prevents wasteful continuation of training while ensuring optimal precision is achieved.

Inventive Principle:
Principle #23Feedback

3Reliability

If training continues beyond the training limit, then no further improvement in detection accuracy is achieved, but computational resources are wasted

Engineering Contradiction:
Improvedetection reliabilityVSAvoidcomputational energy
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The determination unit continuously monitors prediction results and compares them across training iterations. When the feedback indicates that errors and omissions have stabilized and no further improvement is occurring, the system automatically terminates training, preventing waste of computational energy while ensuring detection reliability is optimized.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-evaluation of its own training status through the determination unit, which autonomously assesses whether the training limit has been reached based on stabilization of prediction results. This self-service mechanism eliminates the need for external judgment and automatically prevents unnecessary continuation of training, conserving computational resources.

Inventive Principle:
Principle #25Self-service

AI summary

An information processing method includes acquiring a first prediction result by inputting evaluation data to a first model; determining an anomaly in the first prediction result based on the first prediction result and reference information; acquiring a second model based on the determination result; acquiring a second prediction result by inputting the evaluation data to the second model; determining an anomaly in the second prediction result based on the second prediction result and the reference information; acquiring a third model based on the determination result; acquiring a third prediction result by inputting the evaluation data to the third model; determining an anomaly in the third prediction result based on the third prediction result and the reference information; and if the anomaly in the third prediction result is recognized as being identical to the anomaly in the first prediction result, outputting information about a training limit of the first model.
