Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current AI/ML models lack the ability to explain causal relationships in inference results and may malfunction undetected during deployment due to errors in development and data input, leading to varying performance measurements that depend on training timing and environmental factors.
Innovation Solution
A method and apparatus for verifying AI/ML model reliability using a digital twin network that replicates the actual network environment, allowing for the duplication and forwarding of network traffic to simulate the AI/ML model's performance and detect potential issues before deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If AI/ML models are deployed directly after training, then deployment speed is improved, but model reliability deteriorates due to undetected malfunctions and performance variations
Solution Approach 1:
The patent creates a digital twin network that replicates the actual network environment before AI/ML model deployment. This preliminary action allows comprehensive reliability verification including causality explanation validation, counterfactual inference testing, and performance measurement under various conditions. By performing these verification actions in advance on the digital twin, the system identifies and resolves potential malfunctions before actual deployment, thus improving model reliability without significantly extending deployment time.
2Reliability
If comprehensive model verification is performed, then model reliability is improved, but verification complexity increases
Solution Approach 1:
The patent creates a digital twin as a simplified copy of the actual network environment. This digital twin replicates essential network characteristics, traffic patterns, and operational conditions but with reduced complexity compared to the full production system. By performing comprehensive verification on this simplified copy rather than the complex actual system, the patent achieves thorough model validation while managing verification system complexity through the abstracted digital representation.
Solution Approach 2:
The verification process is segmented into distinct modular components: causality explanation verification, counterfactual inference testing, performance measurement, and reliability assessment. Each module independently verifies specific aspects of the AI/ML model. This segmentation allows the complex verification task to be broken down into manageable, independently testable units, reducing overall verification system complexity while maintaining comprehensive reliability checking.
3Adaptability or versatility
If AI/ML models operate in complex network environments, then functionality is improved, but undetected malfunctions increase due to development errors and data input problems
Solution Approach 1:
The digital twin network serves as an intermediary between the AI/ML model development environment and the actual production network. It provides a controlled intermediate environment that replicates complex network conditions including various traffic patterns, device configurations, and operational scenarios. By testing models in this intermediary digital twin environment, the system detects malfunctions caused by development errors and data input problems before models encounter real production traffic, thus reducing harmful undetected malfunctions while maintaining full network functionality.
