Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If machine learning algorithms are applied to predict SARS-CoV-2 variants, then prediction accuracy is improved, but computational resource requirements increase
Solution Approach 1:
The patent divides the genome samples into N groups and processes them in parallel using multiple linear support vector machines. This segmentation approach allows the system to handle large volumes of genomic data by breaking it into manageable chunks, reducing the computational burden on any single processing unit while maintaining overall prediction accuracy.
Solution Approach 2:
The patent employs a representative selection algorithm that identifies and processes only the most relevant genomic features and mutations rather than analyzing every possible data point. This partial action approach focuses computational resources on the most discriminative features, achieving accurate variant prediction without the excessive computational cost of exhaustive analysis.
2Reliability
If comprehensive genomic data is analyzed to improve variant prediction, then prediction reliability is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary filtering and selection of representative genome samples before the main prediction analysis. The representative selection algorithm pre-identifies high-quality genomic isolates with phenotypic statuses, preparing the data in advance so that the subsequent machine learning processing can proceed more quickly without sacrificing prediction reliability.
Solution Approach 2:
The system automatically assesses identified genomic isolates using performance metrics to determine their quality and relevance. This self-service mechanism allows the algorithm to autonomously filter and prioritize data without requiring extensive manual preprocessing, reducing processing time while maintaining high prediction reliability through automated quality control.
3Measurement precision
If linear support vector machines are trained with multiple genome samples, then predictive power is improved, but computational complexity increases
Solution Approach 1:
The patent trains multiple linear support vector machines on different groups of genome samples rather than using a single complex model on all data. This segmentation into parallel processing groups reduces the computational complexity of each individual model while collectively achieving high predictive power through the ensemble of simpler models.
