Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a prediction model is trained using whole histological slide images and clinical information, then the accuracy of relapse risk prediction is improved, but the device complexity increases
Solution Approach 1:
The system segments the complex prediction task into distinct components: cell detection module, tissue segmentation module, feature extraction module, and prediction model module. Each module processes specific aspects of the histological images and clinical data independently, then integrates results to produce the final relapse risk prediction. This segmentation manages complexity while maintaining high prediction accuracy through specialized processing at each stage.
Solution Approach 2:
The system introduces intermediate processing layers between raw data input and final prediction output. These intermediaries include detected cells, segmented tissues, and extracted features (morphological, textural, color) that bridge the gap between complex input data and the prediction model. These intermediaries simplify the processing pipeline while preserving critical information for accurate relapse risk assessment.
2Reliability
If multiple features are extracted from cells and tissues in histological images, then the prediction model performance is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary processing of histological images before main prediction analysis. Cell detection and tissue segmentation are executed in advance to identify regions of interest and extract relevant features (morphological, textural, color) beforehand. This preliminary action prepares data in an optimized format, reducing the computational burden during the actual prediction phase and enabling comprehensive feature analysis without excessive processing time.
Solution Approach 2:
The system extracts multiple types of features (morphological, textural, color) from cells and tissues, going beyond minimal requirements. This excessive feature extraction ensures comprehensive characterization of histological samples, improving prediction model reliability. The system processes more features than strictly necessary but filters and prioritizes them efficiently in the prediction model to maintain acceptable processing times.
