Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual dataset labeling is used, then data quality can be ensured, but the process becomes intrusive and label intensive, making it infeasible for large datasets
Solution Approach 1:
The patent uses synthetic data generation to create artificial data points that replicate real data characteristics. The generator network produces synthetic samples that can be labeled automatically, replacing the need for manual labeling of all data points while maintaining data quality for training purposes.
Solution Approach 2:
The system employs self-supervised learning where the model learns to represent data without requiring external labels. The autoencoder architecture enables the system to create its own training data through unsupervised pre-training, eliminating the need for manual annotation processes.
2Measurement precision
If large datasets are used for AI model training, then model accuracy improves, but the manual labeling process becomes increasingly resource intensive and time consuming
Solution Approach 1:
The patent performs unsupervised pre-training of the autoencoder on large unlabeled datasets before supervised training. This preliminary action allows the model to learn robust feature representations from abundant data without time-consuming labeling, establishing a foundation that accelerates subsequent supervised learning.
Solution Approach 2:
The system transitions between different training modes - starting with unsupervised pre-training using only input data, then transitioning to supervised training with synthetic labeled data. This parameter change in the training process enables efficient utilization of large datasets by first leveraging their structural information without labels.
3Measurement precision
If domain specific labeling is performed manually, then labeling accuracy can be maintained, but the process becomes intrusive and not scalable
Solution Approach 1:
The generator network creates synthetic data points that replicate the statistical properties and domain characteristics of real data. These synthetic copies can be automatically labeled by the model itself, maintaining domain-specific accuracy while enabling unlimited scalability without human annotators.
Solution Approach 2:
The patent introduces synthetic data as an intermediary between real domain-specific data and the training process. The synthetic data serves as a bridge that preserves domain characteristics while enabling automated processing, allowing the system to scale indefinitely without losing domain adaptability.
