Engineering Contradiction Analysis
1Reliability
If traditional capsule networks use static routing coefficients, then the routing process is simple to implement, but the feature integration and routing performance are insufficient
Solution Approach 1:
The patent transforms static routing coefficients into dynamic routing coefficients that adapt based on input data characteristics. The GAN-generated features enable the routing mechanism to dynamically adjust coefficients during inference, improving feature integration and routing performance while maintaining computational efficiency through pre-generated feature libraries.
Solution Approach 2:
The patent pre-generates synthetic features using GANs during the training phase and stores them in a feature library. This preliminary action allows the capsule network to access diverse, informative features during routing without performing complex real-time generation, thus improving routing performance without proportionally increasing inference complexity.
2Adaptability or versatility
If capsule networks rely on limited feature representation, then the model is simpler to train, but the generalization capability is reduced
Solution Approach 1:
The patent uses GANs to generate synthetic copies of training features that capture the underlying data distribution. These copied features are stored in a library and used during routing to enhance feature diversity and improve generalization without requiring additional real training data, thus increasing adaptability without proportionally increasing training data requirements.
Solution Approach 2:
The patent transforms the feature representation by generating synthetic features with varied parameters through GANs. This changes the parameter space available to the capsule network, providing more diverse feature representations that improve generalization capability while maintaining a manageable feature quantity through efficient storage and retrieval mechanisms.
3Measurement precision
If capsule networks use comprehensive feature integration, then the routing accuracy improves, but the training complexity increases
Solution Approach 1:
The patent performs feature generation and integration preparation during the training phase by pre-generating synthetic features and building the feature library. This preliminary action reduces the computational burden during inference, allowing comprehensive feature integration to achieve high routing accuracy without proportionally increasing real-time training complexity.
Solution Approach 2:
The patent introduces a feature library as an intermediary between the GAN generator and the capsule routing mechanism. This intermediary stores pre-processed synthetic features and provides efficient access during routing, enabling comprehensive feature integration for high routing accuracy while managing training and inference complexity through organized feature storage and retrieval.
