Engineering Contradiction Analysis
1Measurement precision
If multiplexed imaging is used to analyze tissue samples, then measurement precision and diagnostic accuracy are improved, but device complexity and data processing requirements increase
Solution Approach 1:
The patent segments the complex multiplexed image analysis task into distinct processing stages: image preprocessing, cell segmentation, feature extraction, and machine learning classification. Each stage handles specific aspects of the data, breaking down the overall complexity into manageable components that can be processed sequentially
Solution Approach 2:
The patent introduces machine learning models as intermediary components between the raw multiplexed image data and the diagnostic output. These models serve as mediators that automatically learn and extract relevant features from the complex images, reducing the need for manual feature engineering and simplifying the overall processing pipeline
2Measurement precision
If machine learning models are implemented for predicting disease progression, then diagnostic accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal machine learning framework that can handle multiple diagnostic tasks including disease progression prediction, treatment response assessment, and biomarker identification. The same core processing pipeline and model architecture are applied across different clinical scenarios, reducing overall system complexity through reuse of proven components
Solution Approach 2:
The patent utilizes parameter changes in the machine learning models, specifically adjusting hyperparameters and model configurations to optimize performance for different types of multiplexed imaging data. This allows the system to adapt to varying data characteristics without requiring fundamentally different processing approaches for each case
