Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration of image analysis workflow is used, then flexibility and adaptability are maintained, but operator expertise and time consumption increase significantly
Solution Approach 1:
The system performs self-configuration by automatically selecting and optimizing image analysis workflows based on input images and hypotheses, eliminating the need for manual operator intervention in workflow setup while maintaining adaptability to different biological processes
Solution Approach 2:
The machine learning models are pre-trained on large datasets of biological images and hypotheses, enabling them to automatically configure appropriate workflows without requiring operators to manually set up each analysis pipeline from scratch
2Extent of automation
If automated machine-learning configuration is used, then ease of operation improves, but system complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: a first machine learning model for workflow configuration and a second machine learning model for hypothesis prediction, allowing each component to be independently trained, optimized, and replaced without affecting the entire system
Solution Approach 2:
The first machine learning model acts as an intermediary that translates user hypotheses into specific image analysis workflow configurations, which are then executed by the second model to generate predictions, simplifying the overall automation process
3Reliability
If end-to-end training of multiple models is used, then workflow suitability for hypothesis testing improves, but training time and computational resources increase
Solution Approach 1:
The first machine learning model is pre-trained to recognize patterns between hypotheses and appropriate workflow configurations, while the second model is pre-trained for hypothesis prediction, allowing the system to achieve high accuracy without extensive end-to-end training for each new application
Solution Approach 2:
The system uses feedback from the second model's prediction accuracy to refine the workflow configuration generated by the first model, creating an iterative optimization process that improves reliability while distributing the training burden across multiple smaller training cycles
