Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If hand-crafted features are used for scene recognition, then the system can operate with simpler architecture, but the system suffers from overfitting and large reconstruction errors
Solution Approach 1:
The patent replaces hand-crafted feature extraction with a deep convolutional neural network (DCNN) that automatically learns features from images. This substitution of manual feature engineering with automated deep learning achieves better recognition accuracy while managing complexity through modular architecture design.
Solution Approach 2:
The patent transforms the feature representation space by using DCNN to learn optimal feature parameters automatically. The system changes from fixed hand-crafted features to adaptive learned features, and further reduces dimensionality through autoencoders to minimize reconstruction error while maintaining recognition performance.
2Measurement precision
If deep convolutional neural network is used for scene classification, then the accuracy of scene recognition is improved, but the computational complexity and training time increase
Solution Approach 1:
The patent segments the complex DCNN training process into distinct phases: pre-training with autoencoders for feature extraction, followed by fine-tuning for classification. This segmentation allows manageable training complexity while achieving high accuracy through staged optimization.
Solution Approach 2:
The patent performs preliminary pre-training of the DCNN using autoencoders to learn robust feature representations before the actual classification training. This preliminary action prepares the network with useful feature detectors, reducing the complexity and time required for subsequent classification task training.
3Device complexity
If traditional image recognition systems are used, then the system structure is simpler, but the system cannot continuously learn from new images uploaded to the Internet
Solution Approach 1:
The patent implements a dynamic system where the DCNN can be continuously retrained and adapted to new images uploaded to the Internet. The system transitions from static hand-crafted features to dynamic learned features that evolve with new data, enabling continuous adaptation while managing complexity through incremental learning approaches.
4Speed
If hand-crafted features are used for image similarity matching, then the processing speed is faster, but the reconstruction error increases significantly
Solution Approach 1:
The patent changes the feature representation parameters by using DCNN extracted features instead of hand-crafted features. The autoencoder component further optimizes these parameters by learning an efficient compressed representation that minimizes reconstruction error, achieving both accuracy and reasonable processing speed.
