Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual user intervention is used to create segmentation masks for training data, then the training data can be generated, but the process is labor-intensive and prone to imprecision
Solution Approach 1:
The system uses the trained machine learning model to automatically generate segmentation masks for new images, allowing the model to serve itself by producing training data without external manual intervention. The model iteratively refines its own training data by generating segmentation masks that are then used to retrain and improve the model.
Solution Approach 2:
The parameterized model acts as an intermediary between the initial segmentation mask and the final training data. It adjusts geometric parameters of the segmentation mask to better match the actual objects in the image, producing refined segmentation masks that serve as high-quality training data without requiring manual drawing.
2Adaptability or versatility
If more training data is added to cover novel measurement situations, then the model's generalizability improves, but the manual effort and time required increases
Solution Approach 1:
The system automatically generates training data for novel situations by using the model to create segmentation masks for new images, eliminating the need for manual annotation of each new scenario. This self-service approach enables rapid adaptation to novel measurement situations while maintaining high productivity.
Solution Approach 2:
The system performs preliminary action by pre-adjusting the parameterized model based on the initial segmentation mask before finalizing the training data. This preliminary adjustment of geometric parameters ensures that the training data is pre-optimized for the specific measurement situation, improving model generalizability without requiring extensive manual effort.
3Measurement precision
If a parameterized model is used to adjust the segmentation mask, then the precision of training data improves, but the device complexity increases
Solution Approach 1:
The system uses parameter changes by adjusting geometric parameters (such as position, size, shape) of the parameterized model to match the segmentation mask. This approach improves precision by systematically varying parameters to optimize the fit between the model and the actual objects, while keeping the complexity manageable through focused parameter adjustment rather than full manual annotation.

AI summary
A microscopy system for generating training data for a machine learning model comprises a microscope configured to capture an image. The microscopy system further comprises a computing device configured to generate a segmentation mask based on the image, adjust a pattern described by a parameterized model to the segmentation mask, generate an updated segmentation mask using the adjusted pattern, and incorporate the updated segmentation mask or an image derived from the same in the training data.
