Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single model is trained on sparse image data, then the model structure remains simple, but the classification accuracy deteriorates due to overfitting
Solution Approach 1:
The patent divides a single complex model into multiple simpler expert models, each trained on different auxiliary outputs or inputs. This segmentation allows each expert to specialize in specific aspects of image classification, reducing individual model complexity while collectively improving overall classification accuracy through their diverse predictions.
Solution Approach 2:
The patent creates a composite classification system by combining predictions from multiple expert models with different architectures and training focuses. This composite approach integrates diverse model strengths, producing more reliable classifications on sparse data than any single model could achieve alone.
2Reliability
If multiple base learner models are combined in MoE architecture, then classification performance improves, but system complexity increases
Solution Approach 1:
The system segments the classification task across multiple expert models, each handling specific auxiliary outputs or inputs. This division allows independent training and optimization of each expert, managing system complexity through modular design while achieving improved classification performance through their combined predictions.
Solution Approach 2:
The MoE architecture creates a universal classification system where multiple expert models with different specializations work together. Each expert model serves multiple functions by contributing to different aspects of the classification task, allowing the system to handle diverse classification challenges with a unified framework.
3Adaptability or versatility
If base learner models are trained on different auxiliary outputs, then generalization capability improves, but training complexity increases
Solution Approach 1:
The training process is segmented into multiple specialized training tasks, where each expert model is trained on different auxiliary outputs or inputs. This segmentation enables focused optimization for each expert's specific function, improving overall generalization capability while managing training complexity through divided responsibilities.
Solution Approach 2:
Each expert model develops local quality by specializing in specific auxiliary outputs or inputs during training. This localized expertise allows each model to become highly proficient at its specific task, and when combined, the collective generalization capability exceeds that of a single general-purpose model.
