Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional image recognition methods are used for behavior detection, then the system can detect student behaviors, but the hardware requirements are high and recognition accuracy is insufficient
Solution Approach 1:
The patent changes the parameter of the neural network model by introducing depth tensor train decomposition, transforming the traditional flat fully connected layers into a depth-wise factorized structure. This parameter change reduces the computational complexity and hardware requirements while maintaining or improving recognition accuracy through the low-rank approximation capability of tensor train decomposition
Solution Approach 2:
The patent segments the fully connected layers of the neural network into depth-wise separated tensor train components. By dividing the monolithic layer into multiple smaller tensor train blocks with low-rank factorization, the system reduces memory requirements and computational burden, enabling deployment on devices with limited hardware resources
2Reliability
If comprehensive behavior detection and facial expression recognition are implemented, then teaching quality and efficiency are improved, but the system complexity increases
Solution Approach 1:
The patent creates a universal teaching assistance system that performs multiple functions including behavior detection, facial expression recognition, and learning state analysis using a single integrated neural network architecture with depth tensor train decomposition. This multi-functional approach improves teaching quality comprehensively while managing system complexity through a unified rather than separate-component architecture
Solution Approach 2:
The patent replaces complex mechanical or manual teaching assistance methods with an automated computer vision system using depth tensor train network models. This substitution automates behavior and expression analysis, improving reliability of teaching quality assessment while the efficiency gains offset the initial system complexity
