Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional attribute extraction systems are used, then the system complexity is low, but the measurement precision of attribute prediction deteriorates
Solution Approach 1:
The system segments attribute extraction into multiple specialized neural networks: a first neural network for extracting first attributes and a second neural network for extracting second attributes. This segmentation allows each network to specialize in specific attribute types, improving overall prediction accuracy while managing system complexity through modular architecture.
Solution Approach 2:
The system transitions from traditional single-attribute extraction to multi-attribute extraction by adding dimensional complexity. It extracts both first attributes (e.g., object-level properties) and second attributes (e.g., part-level properties), creating a multi-dimensional attribute space that significantly improves comprehensive prediction accuracy.
2Adaptability or versatility
If conventional attribute extraction systems are used, then the device complexity is low, but the adaptability to arbitrary digital images deteriorates
Solution Approach 1:
The system achieves universality by designing neural networks that can handle multiple attribute types and arbitrary digital images. The first and second neural networks are trained on diverse datasets and can predict various attribute categories (color, shape, texture, etc.), making the system adaptable to different domains and image types beyond its training data.
Solution Approach 2:
The system employs dynamic attribute extraction where the neural networks adapt their predictions based on the input image characteristics. The multi-attribute framework allows the system to dynamically select and extract relevant attributes from different hierarchical levels, enhancing flexibility for arbitrary digital images with varying content and complexity.
3Measurement precision
If multi-attribute contrastive classification neural network is used, then the measurement precision of attribute extraction improves, but the device complexity increases
Solution Approach 1:
The system implements contrastive classification with feedback mechanisms where the neural networks learn from prediction errors and adjust their parameters accordingly. The contrastive loss function provides feedback signals that guide the networks to distinguish between correct and incorrect attribute predictions, significantly improving mean average precision through iterative optimization.
Solution Approach 2:
The system combines multiple neural networks with different functionalities into a composite system. The first neural network handles first attributes while the second neural network handles second attributes, creating a composite architecture that leverages the strengths of each component to achieve superior overall prediction accuracy.
4Productivity
If conventional systems are used, then the ease of operation is maintained, but the productivity in handling diverse features and occlusions deteriorates
Solution Approach 1:
The system segments the attribute extraction task into multiple specialized networks that handle different attribute types and hierarchical levels. This segmentation enables the system to process diverse features and occlusions more effectively by assigning specific processing responsibilities to each network, thereby increasing the coverage of attribute-object pairings.
Solution Approach 2:
The system introduces intermediate processing layers and feature extraction mechanisms that mediate between the input image and final attribute predictions. These intermediaries help handle diverse features and occlusions by extracting robust intermediate representations that capture essential object characteristics even under challenging conditions.
