Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional machine learning systems are used to generate predictions, then operational simplicity is maintained, but prediction accuracy deteriorates
Solution Approach 1:
The system is divided into multiple independent machine learning models, each specialized for a specific domain (e.g., protein binding affinity prediction, compound property prediction). This segmentation allows each model to be optimized for its specific task, improving overall prediction accuracy while maintaining manageable complexity through modular architecture.
Solution Approach 2:
A tractability machine learning model serves as an intermediary that generates tractability scores to assess the reliability of predictions from other models. This intermediary layer filters and weights predictions before final decision-making, improving accuracy by accounting for model uncertainty without requiring complete redesign of the prediction system.
2Measurement precision
If large volumes of training data are used to improve prediction accuracy, then measurement precision improves, but loss of time and computational resources increases
Solution Approach 1:
Instead of training all models exhaustively on complete datasets, the system uses partial training approaches where models are trained on representative subsets of data or using incremental learning. This reduces training time while maintaining sufficient accuracy for practical applications, balancing computational investment with prediction quality.
Solution Approach 2:
The system performs preliminary data processing and feature extraction before model training, and uses pre-trained models where applicable. This preliminary action prepares data in advance and leverages existing knowledge, reducing the computational burden and time required during actual model training and prediction phases.
3Reliability
If conventional machine learning systems are used, then device complexity is maintained, but reliability of predictions deteriorates
Solution Approach 1:
The tractability machine learning model provides feedback on the reliability of predictions generated by other models. By continuously assessing prediction quality and adjusting tractability scores based on model performance, the system improves overall reliability through iterative refinement without requiring complete system redesign.
Solution Approach 2:
The system combines multiple machine learning models with different strengths and characteristics into a composite prediction system. Each model contributes its specialized capabilities, and their predictions are integrated through the tractability scoring mechanism, creating a more reliable overall system than any single model could achieve alone.
4Measurement precision
If multi-domain machine learning models are implemented to improve prediction accuracy, then measurement precision improves, but operational flexibility deteriorates
Solution Approach 1:
The multi-domain prediction system is segmented into independent, specialized models for different domains (protein interactions, compound properties, etc.). This segmentation maintains operational flexibility by allowing individual models to be selected and executed based on specific prediction needs, while still achieving high accuracy through domain-specific expertise of each model.
Solution Approach 2:
The tractability machine learning model serves as a universal intermediary that can assess the reliability of predictions from any of the specialized domain models. This multi-functional component maintains operational flexibility by providing a consistent evaluation framework across different domains without requiring domain-specific customization of the assessment mechanism.
