Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-determined and fixed backbone architectures are used, then implementation simplicity is maintained, but adaptability to novel tasks deteriorates
Solution Approach 1:
The patent implements dynamic architecture adaptation by training adaptive controllers that modify the backbone architecture based on support data from few-shot tasks. The system transitions from static pre-determined architectures to dynamic architectures that can be regressed and adapted during meta-learning, allowing the model to optimize its structure for each novel task while maintaining implementation feasibility through automated controller-based adaptation
Solution Approach 2:
The system employs self-service mechanisms where the adaptive controllers automatically regress and adapt the architecture from support data without requiring manual intervention or fine-tuning. The meta-learning framework enables the model to self-optimize its architectural parameters based on the characteristics of novel tasks, making the system self-adapting rather than relying on external architecture design for each task
2Reliability
If large architectures pre-trained on training portions are used, then feature transferability is improved, but computational resources and training time increase
Solution Approach 1:
The patent applies preliminary action by pre-training large architectures on the training portion of FSL datasets before meta-learning. This pre-training establishes strong foundational features that are more easily transferable to novel few-shot tasks, reducing the time needed for task-specific adaptation while maintaining high transferability. The adaptive controllers then build upon this pre-established foundation rather than learning from scratch
Solution Approach 2:
The system changes parameters by transitioning from fixed architectural parameters to adaptive parameters that are regressed from support data. The adaptive controllers learn to modify architectural parameters dynamically based on task characteristics, allowing the model to maintain strong feature transferability from large pre-trained architectures while adapting parameters efficiently for each novel task without requiring extensive retraining time
