Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual expert assessment is used to select de-identification strategies, then accuracy and reliability of strategy selection is improved, but time consumption and cost increase significantly
Solution Approach 1:
The system enables automated self-assessment of de-identification strategies through AI models that independently evaluate data characteristics and recommend appropriate strategies without requiring manual expert intervention. The reinforcement learning model continuously learns from feedback to improve its own decision-making capabilities.
Solution Approach 2:
The patent replaces the mechanical process of manual expert review with an automated AI-based system. The reinforcement learning model substitutes human experts by learning optimal strategy selection through interaction with the environment and receiving feedback on the effectiveness of recommended strategies.
2Reliability
If third party subject matter experts are involved in de-identification processes, then strategy selection quality is improved, but data security risks and additional costs increase
Solution Approach 1:
The organization's own AI system performs the assessment and recommendation functions that previously required external experts. This eliminates the need to share sensitive data with third parties while maintaining the ability to select appropriate de-identification strategies through automated analysis of data characteristics.
3Reliability
If multiple de-identification techniques are evaluated and tested, then the best strategy is identified, but the process becomes time-consuming and complex
Solution Approach 1:
The reinforcement learning model incorporates feedback mechanisms where the effectiveness of recommended strategies is evaluated and fed back into the system. This feedback loop allows the model to learn from outcomes and continuously improve its recommendation accuracy without requiring manual evaluation of multiple techniques.
Solution Approach 2:
The system changes the approach from manually evaluating multiple techniques to using AI-driven parameter optimization. The reinforcement learning model automatically adjusts and optimizes strategy parameters based on learned patterns from data characteristics and historical performance, simplifying the complex evaluation process.
4Productivity
If automated de-identification systems are implemented, then efficiency and speed are improved, but accuracy and adaptability may deteriorate without expert knowledge
Solution Approach 1:
The patent replaces traditional rule-based automated systems with reinforcement learning-based AI models. This substitution enables the system to maintain high processing speed while improving adaptability and accuracy by learning from environmental feedback rather than relying on pre-programmed rules.
Solution Approach 2:
The system transitions from static rule-based automation to dynamic learning-based automation. The reinforcement learning model continuously adapts its behavior based on feedback from the environment, allowing it to maintain high productivity while improving accuracy and adaptability over time through continuous learning.
Data Source
AI summary
The disclosed system and method provide an artificial intelligence (AI) model trained using clustering and reinforcement learning. Data in a dataset can be loaded for de-identification, along with data scope answers. The data can be audited, and once audited, the audited data and the data scope answers can be provided to a strategy recommendation engine including the trained AI model. The engine can determine a cluster corresponding to the dataset and assesses strategies for data de-identification based on the determined cluster. The strategies can be ranked and provided as output, providing the ability to better de-identify the dataset by indicating which techniques will be the most effective. Additionally, the system and method can automatically implement a top-ranked strategy satisfying certain criteria as a determined optimal approach for data de-identification. Clustering and reinforcement learning may efficiently and automatically glean information from unlabeled data. Feedback-based retraining may improve performance further.
