Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a challenger model is deployed to replace the primary model, then model performance may be improved, but the risk of deploying a poorly performing model increases

Engineering Contradiction:
Improvemodel performanceVSAvoidrisk of deploying inferior model
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary comparison of performance metrics between the challenger model and primary model before deployment. By evaluating multiple metrics (accuracy, precision, recall, F1-score, etc.) in advance and requiring the challenger to outperform the primary model across specified thresholds, the system prevents premature or incorrect model deployment, thereby reducing the risk of deploying an inferior model while still enabling performance improvements.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If comprehensive validation processes are performed before model switching, then deployment reliability is improved, but computational resource utilization increases

Engineering Contradiction:
Improvedeployment reliabilityVSAvoidcomputational resource utilization
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs a partial validation process by evaluating only the necessary performance metrics required for model comparison rather than comprehensive validation of all model aspects. The validation is tailored to compare specific metrics (accuracy, precision, recall, etc.) between models, avoiding unnecessary computational overhead while ensuring sufficient reliability for informed deployment decisions.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system changes the validation approach from comprehensive model validation to parameter-specific performance metric comparison. By focusing on key performance parameters (accuracy, precision, recall, F1-score, processing time) rather than exhaustive validation, the system reduces computational resource utilization while maintaining deployment reliability through targeted metric evaluation.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If multiple performance metrics are compared between models, then comparison accuracy is improved, but the complexity of monitoring increases

Engineering Contradiction:
Improvecomparison accuracyVSAvoidmonitoring complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the model comparison process into distinct performance metric evaluations (accuracy, precision, recall, F1-score, processing time, resource utilization). Each metric is calculated and compared independently, allowing for precise measurement of model performance across multiple dimensions while organizing the monitoring complexity into manageable, separate evaluation components that can be assessed systematically.

Inventive Principle:
Principle #1Segmentation

AI summary

Comparing a challenger model with a primary model is provided herein. In an embodiment, a system comprises one or more processors, coupled to memory, configured to determine, based on a comparison of a first model that is deployed as a primary model with a second model that is acting as a challenger model, that the second model performs better than the first model based on at least one performance metric; determine, based on a comparison of a characteristic of the first model with a characteristic of the second model, to skip a validation process for the second model; and establish the second model as the primary model in the deployment to replace the first model in the deployment.
