Engineering Contradiction Analysis
1Reliability
If a deep learning neural network uses a fully-connected internal architecture to achieve high performance, then the accuracy and capability of the network are improved, but the computational resource consumption increases excessively and the device complexity increases
Solution Approach 1:
The neural network is segmented into a common backbone that performs shared feature extraction and multiple task-specific heads that perform specialized inferencing tasks. This segmentation allows the common backbone to be computed once and reused across multiple tasks, reducing redundant computational operations while maintaining high accuracy for each specific task.
Solution Approach 2:
The common backbone is designed to serve multiple functions by extracting general features that are applicable to various medical image analysis tasks. This universal component processes input images once and provides feature representations that can be utilized by multiple task-specific modules, thereby reducing overall computational resource consumption.
2Reliability
If a deep learning neural network uses a fully-connected internal architecture, then the network achieves high performance, but the device complexity and retraining complexity increase
Solution Approach 1:
The network is divided into independent modular components (common backbone and task-specific heads) that can be trained and updated separately. This modular segmentation reduces retraining complexity because changes to one task-specific head do not require retraining the entire network, only the affected module needs to be retrained.
Solution Approach 2:
The architecture enables dynamic configuration where task-specific components can be added, removed, or modified independently based on requirements. This dynamic modularity simplifies the retraining process as individual components can be updated without affecting the stability of other parts of the system.
3Adaptability or versatility
If multiple separate deep learning models are used for different inferencing tasks, then each task can be optimized independently, but the memory usage and computational overhead increase excessively
Solution Approach 1:
Multiple task-specific inferencing modules are merged into a single unified neural network architecture that shares a common backbone. This merging allows the system to maintain the adaptability and optimization capabilities of multiple specialized models while reducing memory consumption by sharing the common feature extraction components across all tasks.
