Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used for training machine learning models, then model accuracy can be achieved through extensive human labeling, but the process becomes time-consuming and resource-intensive
Solution Approach 1:
The system enables self-service labeling where the machine learning model automatically labels its own predictions without requiring human annotators. The model uses spatial information and environmental context to generate labels for training data, eliminating the time-consuming human labeling process while maintaining training accuracy
Solution Approach 2:
The system performs preliminary actions by pre-processing environmental data and spatial information before model training. By preparing labeled data in advance using automated methods and spatial reasoning, the system reduces the overall training time and resource requirements while maintaining model performance
2Measurement precision
If human workers are used for labeling vision data, then accurate labels can be obtained, but the cost and time required increase significantly
Solution Approach 1:
The system replaces human workers with automated self-service labeling mechanisms. The machine learning model generates its own labels by processing spatial information and environmental data, achieving both high label accuracy and improved productivity by eliminating human labor constraints
Solution Approach 2:
The system substitutes the mechanical process of human annotation with automated computational methods. By using algorithms to process spatial data and generate labels automatically, the system maintains labeling accuracy while dramatically improving efficiency and productivity
3Adaptability or versatility
If average performance measurements are used across different environments, then model performance can be evaluated generally, but performance in specific environments cannot be predicted accurately
Solution Approach 1:
The system applies local quality by evaluating model performance specifically for each environment rather than using average metrics across all environments. By analyzing spatial information and environmental characteristics unique to each location, the system provides precise predictions for environment-specific performance while maintaining general adaptability
