Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard machine learning classification techniques are used for spectral object classification, then the classification process can be performed with conventional methods, but the accuracy is insufficient for complex spectral objects with varying constituents and forms
Solution Approach 1:
The patent segments the spectral classification problem into multiple binary decision stages using a sieve-type process. Each stage divides the feature space to separate specific classes or backgrounds, progressively refining classification accuracy for complex spectral objects with varying constituents and forms.
Solution Approach 2:
The patent transforms the high-dimensional spectral data into score distributions through linear transformation operations. This dimensional transformation creates disjoint or sufficiently distinct score distributions that enable accurate classification while handling the complexity of varying spectral constituents.
2Measurement precision
If high-dimensional spectral data is processed directly, then comprehensive spectral information is utilized, but classification accuracy decreases due to the curse of dimensionality and noise sensitivity
Solution Approach 1:
The patent extracts discriminative features from high-dimensional spectral data by projecting onto linear transformation operations that generate score distributions. This extraction process isolates the most informative spectral characteristics while eliminating redundant dimensions and noise, thereby improving classification accuracy.
Solution Approach 2:
The patent performs preliminary linear transformation operations on spectral data before classification to create score distributions. This preliminary processing step pre-separates the feature space in a way that simplifies subsequent binary decision-making and reduces the impact of the curse of dimensionality.
3Measurement precision
If complex neural network architectures are used to handle spectral variability, then classification accuracy may improve, but the system complexity and computational requirements increase significantly
Solution Approach 1:
The patent replaces complex neural network architectures with a sieve-type binary decision ensemble system based on linear transformation operations and score distributions. This substitution maintains classification accuracy for spectral objects with varying constituents while significantly reducing architectural complexity and computational requirements.
4Measurement precision
If iterative filtering of measurement vectors is performed to achieve disjoint score distributions, then classification accuracy improves, but processing time increases
Solution Approach 1:
The patent applies iterative filtering of measurement vectors to achieve disjoint or sufficiently distinct score distributions. The process performs filtering to the extent necessary to separate classes or backgrounds, balancing processing time against classification accuracy by stopping when sufficient separation is achieved.
