Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If models are trained extensively to improve performance on new tasks, then model accuracy improves, but training time and computational resources increase significantly
Solution Approach 1:
The system performs preliminary actions by computing brittleness scores and identifying suitable reference models before actual training begins. This advance preparation allows the system to leverage pre-computed metrics and existing model knowledge, reducing the time and resources needed for full model training while maintaining accuracy.
Solution Approach 2:
The system creates a reference model that copies and stores performance characteristics from previously trained models. By copying relevant information about model behavior and performance across different tasks, the system avoids retraining from scratch and can quickly adapt to new tasks using the copied knowledge.
2Adaptability or versatility
If organizations train many models for different tasks, then task coverage improves, but organizational complexity and resource management difficulty increase
Solution Approach 1:
The system implements a universal reference model that serves multiple functions across different tasks. Instead of maintaining separate models for each task, the reference model provides a unified approach that can be applied universally to evaluate and adapt models for various tasks, reducing organizational complexity while maintaining versatility.
Solution Approach 2:
The system changes the approach from managing multiple complete models to managing a single reference model with computed brittleness scores and performance metrics. By changing the parameters from full model instances to condensed performance characteristics, the system reduces complexity while maintaining the ability to cover multiple tasks.
3Ease of manufacture
If conventional training methods are used without model brittleness assessment, then training process is simple, but model performance on new tasks deteriorates due to brittleness
Solution Approach 1:
The system introduces feedback by computing brittleness scores that measure how well a model performs across different tasks. This feedback mechanism identifies models that are prone to brittleness before they are deployed, allowing the system to select or adjust models to improve performance on new tasks while maintaining relative simplicity in the training process.
4Productivity
If existing models are not evaluated for brittleness, then model selection is fast, but model performance deteriorates due to selecting brittle models for new tasks
Solution Approach 1:
The system performs preliminary evaluation of model brittleness by computing brittleness scores in advance. This preliminary action stores performance characteristics that can be quickly queried during model selection, maintaining fast selection speed while ensuring that non-brittle models are chosen for new tasks, thereby improving reliability.
