Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine learning models are continuously retrained to adapt to data distribution shifts, then model accuracy is improved, but computational resources and time are consumed
Solution Approach 1:
The system performs preliminary monitoring of data distribution shifts and model performance metrics continuously, so that retraining decisions can be made proactively when needed. This allows the system to prepare for potential accuracy degradation before it occurs, rather than reacting after performance drops.
Solution Approach 2:
The system implements feedback loops that continuously monitor data distribution shifts and model performance, using this information to dynamically decide when retraining is necessary. The feedback mechanism compares current performance against baseline metrics and triggers retraining only when degradation is detected, optimizing the balance between accuracy maintenance and computational resource consumption.
2Reliability
If multiple machine learning models are monitored and potentially retrained, then workflow performance is improved, but system complexity increases
Solution Approach 1:
The system segments the monitoring and retraining process into individual model-level components, where each machine learning model is monitored and managed independently. This segmentation allows complex workflows with multiple models to be handled through modular, manageable units, reducing overall system complexity while maintaining high workflow performance.
Solution Approach 2:
The system implements a universal monitoring framework that can handle multiple different types of machine learning models through a common interface and set of tools. This multi-functional approach allows the same infrastructure to monitor and manage diverse models without requiring separate complex systems for each model type, thereby reducing overall system complexity.
3Reliability
If data is accessed for retraining purposes, then model performance is improved, but data privacy and residency issues are exacerbated
Solution Approach 1:
The system introduces an intermediary layer between data sources and the retraining process, which acts as a mediator to handle data access securely. This intermediary component facilitates data sharing while maintaining privacy protections and residency requirements, allowing model retraining to proceed without directly exposing sensitive data to unauthorized access or violation of data sovereignty laws.
