Solution Overview
Problem
Neural network-based approaches for making control decisions or diagnosing faults in mechanical systems are often opaque, making it difficult to understand the reasoning behind decisions, which is a concern for safety-critical applications.
Innovation Solution
A system that generates responses to queries by alternating between selection and inference steps, providing a traceable reasoning process in natural language that justifies the final answer, ensuring transparency and interpretability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a neural network-based approach is used to make control decisions, then the decision-making capability is improved, but the interpretability of the reasoning process deteriorates
Solution Approach 1:
The patent introduces an intermediary component that generates natural language explanations as a mediator between the neural network's internal reasoning process and the external observer. This intermediary translates the network's decisions into human-interpretable language without altering the underlying decision-making capability, thus resolving the contradiction between automation performance and interpretability.
2Productivity
If a neural network is used as a black box for control decisions, then the productivity is improved, but the reliability for safety-critical applications deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where natural language explanations are generated and provided back to users alongside the neural network's decisions. This feedback loop allows users to understand and verify the reasoning process, thereby building trust and reliability for safety-critical applications while maintaining the high productivity benefits of neural network-based decision-making.
