1Productivity
If structural reparameterization is used to merge convolution layers, then computational efficiency is improved, but non-linear components cannot be merged and performance is limited
Solution Approach 1:
The patent merges multiple convolution layers with non-linear activation functions into a single equivalent convolution layer by deriving mathematical relationships between their parameters. This combines both linear and non-linear operations into one unified layer that can be executed efficiently on edge devices while maintaining the performance benefits of complex multi-layer architectures.
Solution Approach 2:
The patent transforms the parameters of multiple convolution layers and non-linear activation functions into equivalent parameters of a single convolution layer through mathematical derivation. By changing and reparameterizing the kernel weights and activation functions, the system achieves both computational efficiency and non-linear processing capability in a unified structure.
2Manufacturing precision
If multiple convolution layers with non-linear activations are used, then model accuracy is improved, but deployment on edge devices becomes inefficient
Solution Approach 1:
The patent combines multiple convolution layers with non-linear activation functions into a single equivalent convolution layer, reducing the number of operations required for inference while preserving the accuracy benefits of the original multi-layer architecture. This merged structure is specifically optimized for efficient deployment on resource-constrained edge devices.
Solution Approach 2:
The patent creates an equivalent copy of the multi-layer architecture's functionality in a single-layer form. By mathematically deriving the equivalent parameters, the system replicates the computational behavior of complex multi-layer models in a simplified single-layer structure that is more efficient for edge device deployment.
3Device complexity
If non-linear components are excluded from reparameterization, then structural simplicity is maintained, but performance ceiling is reached
Solution Approach 1:
The patent extends parameter transformation techniques to include non-linear activation functions, not just linear convolution operations. By deriving how non-linear parameters can be transformed and merged, the system breaks through the performance ceiling of traditional linear-only reparameterization while maintaining structural simplicity through the single-layer output format.
