Engineering Contradiction Analysis
1Quantity of substance
If Euclidean space-based transfer learning techniques are used, then the model can be trained on large-scale data sets, but the model cannot effectively handle complex structures in non-Euclidean spaces such as molecular structure data
Solution Approach 1:
The patent changes the fundamental parameter of the feature space from Euclidean to Riemannian geometry. By representing molecular structures in a Riemannian manifold space instead of Euclidean space, the model can capture the intrinsic geometric relationships of molecular graphs while maintaining the ability to handle large-scale data sets for transfer learning.
Solution Approach 2:
The patent substitutes the traditional Euclidean geometric framework with a Riemannian geometric framework. This replacement enables the model to naturally handle the non-Euclidean nature of molecular structure data while preserving the benefits of transfer learning on large-scale data sets.
2Reliability
If transfer learning is applied to small, complex data sets such as molecular structure data, then the model can leverage knowledge from source tasks, but existing techniques show limitations in handling high-dimensional non-Euclidean problems
Solution Approach 1:
The patent transforms the problem from Euclidean to Riemannian space, enabling effective transfer learning on small, complex molecular structure data sets by capturing their intrinsic geometric properties while providing a unified framework that manages the complexity through mathematical abstraction.
3Adaptability or versatility
If the model is trained to process multi-task for output according to a plurality of domains, then the model can handle diverse tasks, but the model requires large amounts of data which are not always available
Solution Approach 1:
The patent creates a universal Riemannian transfer learning framework that can handle multiple tasks across different domains simultaneously. By using a domain-specific metric learning approach in Riemannian space, the model achieves multi-functionality while being efficient with limited data through geometric knowledge transfer between tasks.
