Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If machine learning models are trained using data transmitted over wireless networks in edge computing environments, then model training can be performed at the edge, but data quality deteriorates due to wireless interference, congestion, packet loss, and frame loss
Solution Approach 1:
The system performs preliminary assessment of network conditions (signal-to-interference-plus-noise ratio, bit error rate, packet loss, frame loss) and image quality (inference confidence scores) before selecting training images. This preliminary evaluation allows the system to proactively avoid using poor-quality data that would result from anticipated transmission issues, thereby resolving the contradiction between edge training efficiency and data quality reliability.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring network performance metrics and image quality indicators, then using this feedback to dynamically adjust training image selection. The feedback loop enables the system to adapt to changing wireless conditions in real-time, ensuring high-quality data is selected for training while maintaining efficient edge computing operations.
2Measurement precision
If large machine learning models are used to improve processing capabilities, then model accuracy increases, but computing resources and data transfer requirements increase
Solution Approach 1:
The system changes the parameter of training data quality by selectively choosing images with high inference confidence scores and good network transmission conditions. This parameter change allows the system to train larger, more accurate models while consuming fewer computing resources, because high-quality training data reduces the need for extensive model iterations and retraining, thereby resolving the contradiction between model accuracy and resource consumption.
3Adaptability or versatility
If frequent data transfer occurs between cloud and edge devices for model training, then model updates can be performed, but networking costs and data transmission overhead increase
Solution Approach 1:
The system performs preliminary evaluation of network conditions and image quality before initiating data transfer for model training. By assessing signal-to-interference-plus-noise ratio, bit error rate, packet loss, and inference confidence scores in advance, the system can determine whether current conditions are suitable for training, thereby avoiding unnecessary data transfers and reducing networking costs while maintaining model update capability.
Solution Approach 2:
The system enables self-service at the edge by autonomously selecting appropriate training images based on local assessments of network conditions and image quality. This self-service capability reduces the need for frequent cloud-edge data transfers, allowing the system to perform model updates independently when conditions permit, thereby reducing networking costs while maintaining adaptability.
