Innovation Solution
A control platform utilizing a natural language engine with a risk-based corpora, a rules engine, and a topic model to generate expected labels for change records, employing supervised and unsupervised learning to classify changes as 'pass', 'fail', or 'suspense' based on similarity and confidence thresholds, ensuring proactive guidance and minimizing future control issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual review of all change records is performed, then accuracy of control verification is improved, but productivity and time consumption are worsened
Solution Approach 1:
The system employs machine learning models that automatically analyze and classify change records without human intervention. The topic model and supervised learning algorithms enable the system to self-evaluate change records, determining pass/fail/suspense classifications autonomously, thus achieving both high accuracy and high productivity simultaneously
Solution Approach 2:
The patent replaces manual mechanical review processes with automated computational systems. Machine learning models, natural language processing, and automated classification algorithms substitute human analysts, enabling rapid processing of large volumes of change records while maintaining consistent accuracy through probabilistic classification
2Productivity
If automated classification is used for all change records, then productivity is improved, but measurement precision and reliability are worsened
Solution Approach 1:
The system incorporates feedback mechanisms where classification results are continuously evaluated and used to retrain and improve the machine learning models. The suspense category serves as a feedback loop, allowing manual review of uncertain cases to generate training data that enhances future automated classification accuracy, thus improving both productivity and precision over time
Solution Approach 2:
The patent employs probabilistic classification with configurable confidence thresholds. By adjusting decision parameters and confidence levels, the system can dynamically balance between automated processing speed and classification accuracy, adapting to different operational requirements while maintaining both productivity and measurement precision
3Reliability
If comprehensive analysis of change records is performed, then reliability of control assurance is improved, but loss of time and complexity are worsened
Solution Approach 1:
The system performs preliminary automated filtering and pre-classification of change records before detailed analysis. By quickly identifying obvious pass/fail cases and routing only uncertain cases to more thorough analysis, the system achieves comprehensive reliability assessment without excessive time investment, processing records in stages of increasing depth
4Measurement precision
If manual verification of change records is performed, then measurement precision is improved, but device complexity and operational complexity are worsened
Solution Approach 1:
The system employs self-service automated classification that handles the majority of verification tasks without human intervention. Machine learning models automatically perform the complex analysis work, reducing both operational complexity and the need for manual verification while maintaining high measurement precision through algorithmic consistency
