Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional meta-learning algorithms are used for training conditional neural processes, then the algorithm can be trained to determine object positions from image data, but the training becomes comparatively complex and leads to overfitting and memorization of training data
Solution Approach 1:
The patent changes the training parameters by introducing functional contrastive learning with specific loss functions (contrastive loss and reconstruction loss) that modify how the neural network learns from data. This approach transforms the training dynamics to prevent overfitting while maintaining performance on new data, directly addressing the contradiction between reliability and training complexity
Solution Approach 2:
The patent introduces an intermediary encoding module that processes image data into latent representations before final prediction. This intermediary layer acts as a mediator that prevents direct memorization of training data while preserving essential features, thereby improving generalization to new data without proportionally increasing training complexity
2Adaptability or versatility
If conventional meta-learning algorithms are used for training conditional neural processes, then the algorithm can process training data correctly, but it does not achieve new results when new data are input
Solution Approach 1:
The patent modifies training parameters by implementing functional contrastive learning with dual loss functions that balance feature extraction and reconstruction. This parameter change enables the model to learn more robust representations that generalize better to new data while maintaining training success, directly resolving the contradiction between adaptability and reliability
Solution Approach 2:
The patent implements feedback mechanisms through the contrastive learning framework where the model receives feedback from both the contrastive loss (comparing encoded representations) and reconstruction loss (comparing original and reconstructed images). This dual feedback system guides the model to learn features that are both discriminative and faithful to the original data, improving generalization without sacrificing training reliability
