Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine unlearning is performed to remove sensitive data influence, then privacy and security are improved, but model performance may deteriorate
Solution Approach 1:
The system automatically evaluates model performance before and after unlearning, using feedback loops to monitor accuracy, fairness, and other metrics. This enables the system to detect performance degradation and trigger retraining or adjustment mechanisms, ensuring model performance is maintained while achieving privacy and security goals.
Solution Approach 2:
The system changes multiple model parameters and hyperparameters during the unlearning process, adjusting learning rates, regularization strengths, and other configuration values to optimize the balance between removing sensitive data influence and preserving overall model performance.
2Reliability
If comprehensive performance evaluation is conducted to ensure model quality, then model reliability is improved, but computational resources and time increase
Solution Approach 1:
The evaluation process is segmented into multiple stages: quick preliminary checks, targeted metric evaluation, and comprehensive analysis only when necessary. This hierarchical evaluation approach ensures model quality is maintained while minimizing unnecessary computational resource consumption.
Solution Approach 2:
The system performs partial evaluation using a subset of critical metrics and data samples initially, then expands to comprehensive evaluation only when performance degradation is detected or regulatory requirements demand full verification, avoiding excessive computational resources for routine checks.

AI summary
Generating performance metrics and recommendations to improve an unlearned model includes executing an unlearning algorithm to expunge the influence on a machine learning model of a selected sample of the machine learning model's training dataset. Executing the unlearning algorithm creates an unlearned model. Performance metrics are generated by a metrics generator for the unlearned model and the machine learning model. Based on the performance metrics, an unlearning analysis is generated by a comparator comparing the performances of the unlearned model and machine learning model. A recommender, based on the unlearning analysis, generates a recommendation recommending a revision to the unlearned model in response to detecting a deviation of more than a predetermined threshold of one or more of the performance metrics of the unlearned model from one or more of the performance metrics of the machine learning model. An evaluator generates an unlearning evaluation of the unlearned model.
