Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If compute and memory constraints are reduced to meet real-time inference requirements, then processing speed is improved, but accuracy deteriorates
Solution Approach 1:
The system dynamically adjusts the confidence threshold based on runtime conditions and feature confidence scores. The threshold is not fixed but adapts to balance speed and accuracy requirements, allowing the system to meet real-time constraints while maintaining acceptable accuracy levels through flexible decision boundaries
Solution Approach 2:
The patent changes the parameter of confidence threshold from a static value to a dynamic parameter that can be adjusted based on system state, feature importance, and performance requirements. This parameter change enables the system to optimize the trade-off between processing speed and accuracy by selecting appropriate threshold values for different operational contexts
2Measurement precision
If compute constraints are increased to improve accuracy, then measurement precision is improved, but productivity deteriorates
Solution Approach 1:
The patent segments the feature processing pipeline into multiple stages with different compute requirements. Not all features are processed with the same level of computational resources - instead, features are prioritized and processed selectively based on their confidence scores and importance, reducing overall compute constraints while maintaining accuracy for critical features
Solution Approach 2:
The confidence scoring mechanism acts as an intermediary that filters and prioritizes features before full processing. By pre-evaluating feature confidence, the system identifies which features require intensive processing and which can be handled more efficiently, thereby maintaining accuracy for important features while improving overall productivity
3Speed
If memory constraints are reduced to meet real-time requirements, then speed is improved, but reliability deteriorates
Solution Approach 1:
The patent extracts and processes only the most relevant features based on confidence scores rather than processing all features uniformly. By taking out and prioritizing high-confidence, high-importance features, the system reduces memory requirements while maintaining reliability for critical decision-making, as low-confidence or low-importance features can be processed with less stringent requirements
Data Source
AI summary
Systems, apparatuses, and methods include technology that extracts a plurality of features from the input data. The technology generates a confidence metric for the plurality of features. The confidence metric corresponds to a degree that at least one feature of the plurality of features is relevant for classification of the input data. The technology categorizes the input data into a category based on the plurality of features and the confidence metric
