Engineering Contradiction Analysis
1Measurement precision
If transfer learning is executed on all pretrained models to evaluate effectiveness, then model selection accuracy is improved, but computational time and resources are significantly increased
Solution Approach 1:
The system performs preliminary evaluation of pretrained models by computing adaptability scores before actual transfer learning execution. This preliminary action filters and ranks models based on predicted performance, allowing the system to select top candidate models without executing full transfer learning on all models, thus reducing computational time while maintaining selection accuracy.
Solution Approach 2:
The system creates a virtual evaluation framework that copies and simulates transfer learning outcomes without actual execution. By evaluating adaptability through computational metrics and simulated performance predictions, the system assesses model suitability without the full computational cost of actual transfer learning, effectively copying the evaluation process to reduce resource consumption.
2Reliability
If adaptability evaluation is performed on all pretrained models, then model suitability is improved, but computational resources are significantly increased
Solution Approach 1:
Instead of performing complete transfer learning evaluation on all pretrained models, the system applies partial evaluation by computing adaptability scores using selected computational metrics and simulated performance predictions. This partial action provides sufficient reliability for model selection without the excessive computational resources required for full evaluation of all models.
Solution Approach 2:
The system changes the evaluation parameters from full transfer learning execution to adaptability score computation based on computational metrics. By modifying the evaluation approach to focus on key parameters such as model architecture characteristics, dataset compatibility metrics, and predicted performance, the system maintains reliability while significantly reducing computational resource consumption.
