Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual labeling is used to train machine learning systems, then training accuracy can be improved, but the time and labor required increases significantly
Solution Approach 1:
The system uses the imaging labels (fluorescent markers) to automatically generate training data by detecting and tracking their positions across video frames. The labeled images are generated automatically by the system itself without requiring external manual annotation, thereby reducing time and labor while maintaining training quality
Solution Approach 2:
The system changes the parameter space by utilizing fluorescent imaging labels as an additional modality. By detecting the positions of these labels in the fluorescence channel and mapping them to the visible light channel, the system automatically generates precise annotations without manual intervention
2Measurement precision
If manual labeling is performed for each new experimental setup, then model accuracy for that setup can be improved, but the process does not scale across different labs and conditions
Solution Approach 1:
The system creates a universal training data generation approach that works across different experimental setups, labs, and conditions. The fluorescent labeling method and automated detection pipeline can be applied universally to any animal movement study, eliminating the need for lab-specific manual labeling while maintaining model accuracy through consistent automated annotation
Solution Approach 2:
The system copies the labeling information from the fluorescence imaging channel to the visible light imaging channel. By detecting label positions in the fluorescence modality and mapping them to corresponding locations in the visible light images, the system automatically generates accurate annotations that can be applied across different experimental conditions without manual intervention
3Adaptability or versatility
If different labs train their own landmark trackers from scratch, then customization to local needs is improved, but the lack of standardization reduces comparability of results
Solution Approach 1:
The system provides a universal standardized pipeline that all labs can adopt. By using fluorescent imaging labels that can be applied to any anatomical landmark and an automated detection system that works across different setups, the system enables standardization while still allowing labs to choose which landmarks to track based on their specific research needs

AI summary
Described herein are systems, software, and methods for generating training datasets for machine learning (ML) applications. The systems, software, and methods generally operate by obtaining first and second pluralities of images of a subject bearing as associated imaging label, identifying locations of the imaging label within the first plurality of images, and using the identified locations to generate a plurality of labeled images based upon the second plurality of images. In this manner, a large collection of labeled images may be collected without the need for manual labeling by a human actor. This large collection of labeled images may then form the training set for training a ML system.
