Solution Overview
Problem
Complex machine learning applications often exhibit 'black box' effects, making it difficult to interpret and understand the relationships between inputs and outputs, especially with large datasets, which hinders the deployment of technical improvements and traceability in machine learning systems.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex machine learning applications are used to handle Big Data, then predictive performance and analysis capability are improved, but interpretability and traceability deteriorate due to black box effects
Solution Approach 1:
The patent introduces an intermediary system comprising a replicator module, translator module, and graphical user interface that acts as a mediator between the complex machine learning model and users. The replicator module creates local and global effect models, the translator module generates explanatory mappings, and the GUI renders visual representations, thereby bridging the gap between black box predictions and human understanding without compromising predictive performance
Solution Approach 2:
The replicator module creates simplified copies or approximations of the complex machine learning model's behavior through local and global effect models. These copies replicate the essential input-output relationships in an interpretable form, allowing users to understand model predictions without directly examining the complex internal structures of the original black box model
2Productivity
If the complexity of machine learning applications increases to handle larger datasets, then analysis capability is improved, but understanding and traceability of computing results deteriorate
Solution Approach 1:
The patent segments the complex machine learning system into multiple interpretable components: the original complex model, local effect models for specific predictions, global effect models for overall behavior, and visual representation layers. This segmentation allows analysis of large datasets while maintaining traceability by breaking down the complex system into understandable parts that can be individually examined and explained
3Ease of operation
If traditional statistical methods are used, then simplicity and interpretability are maintained, but flexibility of modeling and predictive performance deteriorate when dealing with Big Data
Solution Approach 1:
The patent applies local quality by creating local effect models that provide simple, interpretable explanations for specific predictions while the global model handles complex Big Data analysis. This allows different parts of the system to have different qualities: the complex global model handles large-scale pattern recognition, while local models provide simple, understandable explanations for individual predictions, combining the strengths of both simplicity and advanced predictive capability
