Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional statistical methods are used for genome-wide prediction, then the method is simple and easy to implement, but the prediction accuracy is insufficient and important genetic signals are missed
Solution Approach 1:
The patent transforms the prediction approach by changing the mathematical parameters from traditional statistical methods to deep learning neural network parameters, enabling the model to capture non-linear relationships and complex interaction patterns in genome-wide data that traditional methods cannot detect
Solution Approach 2:
The patent creates a composite prediction model that integrates multiple types of genomic data (genotype data, gene expression data, protein interaction data) into a unified deep learning framework, combining different data sources to improve overall prediction accuracy while maintaining implementation feasibility
2Measurement precision
If deep learning methods are applied to genome-wide prediction, then prediction accuracy improves, but model stability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms through iterative training processes where model predictions are continuously evaluated against validation data, and model parameters are adjusted through backpropagation to minimize prediction errors, thereby stabilizing the model while maintaining high accuracy
Solution Approach 2:
The patent applies regularization techniques and cross-validation methods before final model deployment to prevent overfitting and ensure model stability, cushioning against potential instability issues that may arise during实际应用
3Loss of information
If genome-wide data is processed without sparsity processing, then all information is retained, but computational complexity and information loss increase
Solution Approach 1:
The patent extracts and retains only the most informative features from genome-wide data through sparsity processing techniques, removing redundant and noisy information while preserving critical genetic signals, thereby reducing computational complexity without significant information loss
Solution Approach 2:
The patent applies different processing strategies to different portions of the genome data, using sparsity processing selectively on regions with high information density while maintaining full resolution in regions where complete information is critical, optimizing the balance between information retention and computational efficiency
