Engineering Contradiction Analysis
1Reliability
If traditional experimental methods are used to study RNA-protein interactions, then reliability of interaction data is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The patent creates computational copies of experimental interaction data from public databases (CLIP-seq, PAR-CLIP, HITS-CLIP datasets) to build training sets for machine learning models. This allows the system to learn from existing experimental results without performing new expensive experiments, thereby reducing time loss while maintaining reliability through multiple data sources
Solution Approach 2:
The patent replaces mechanical/wet-lab experimental methods with computational machine learning models (SVM, RF, XGBoost, neural networks). The system substitutes physical experimental procedures with algorithmic predictions, dramatically reducing time requirements while maintaining reliable interaction predictions through ensemble modeling and feature engineering
2Productivity
If computational prediction methods are used, then productivity is improved, but measurement precision deteriorates
Solution Approach 1:
The patent merges multiple machine learning models (SVM, Random Forest, XGBoost, neural networks) into an ensemble prediction system. By combining the strengths of different algorithms and integrating multiple feature types (sequence features, structural features, evolutionary features), the system achieves high prediction accuracy while maintaining computational efficiency
Solution Approach 2:
The patent transforms the prediction problem by adding multiple dimensions of features beyond simple sequence data, including k-mer frequencies, secondary structure predictions, conservation scores, and interaction energy calculations. This multi-dimensional feature space enables the model to capture complex interaction patterns with high precision
3Measurement precision
If comprehensive feature extraction is performed, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the feature extraction process into distinct modules: sequence feature extraction (k-mer analysis), structural feature extraction (secondary structure prediction), evolutionary feature extraction (conservation analysis), and interaction energy calculation. Each module independently processes specific aspects, making the complex system manageable and maintainable while achieving comprehensive feature representation
