Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine learning verification methods, particularly those using classifiers, require extensive tuning and adjustments to achieve high accuracy, making it difficult for non-experts to obtain reliable results.
Innovation Solution
A verification device and method that acquires image data, utilizes multiple classifiers trained on different learning data sets to obtain values indicating the possibility of a target event, and specifies the state of the object using a calculation that combines the results from these classifiers, thereby simplifying the process of achieving high accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single classifier is used for verification, then the device complexity is low, but the measurement precision and reliability of verification results are insufficient
Solution Approach 1:
The verification system is segmented into multiple independent classifiers, each trained on different learning data. This segmentation allows each classifier to specialize in particular aspects of the verification task, improving overall measurement precision while maintaining manageable complexity through modular architecture
Solution Approach 2:
Multiple classifiers are merged into a unified verification system where their outputs are combined through aggregation (e.g., averaging or voting). This merging leverages the diverse strengths of each classifier trained on different data, achieving higher verification accuracy than any single classifier could provide alone
2Measurement precision
If multiple classifiers are used to improve verification accuracy, then the measurement precision improves, but the device complexity and difficulty of operation increase
Solution Approach 1:
The multiple classifiers are automatically trained on different learning data sets and integrated into the verification system without requiring manual intervention. The system self-manages the complexity of multiple classifiers through automated data processing and result aggregation, making it easy for users to obtain accurate verification results without needing to understand or configure the underlying classifier mechanisms
3Measurement precision
If more learning data is used to train classifiers, then the measurement precision may improve, but over-learning occurs which decreases accuracy on new data
Solution Approach 1:
The learning data is segmented into multiple distinct data sets, with each classifier trained on a different segment. This segmentation prevents any single classifier from over-learning on a comprehensive data set, as each classifier only sees a portion of the total data, thereby improving generalization capability while maintaining accuracy
Solution Approach 2:
The system changes the parameter of learning data composition by training different classifiers on different data sets rather than training a single classifier on all data. This parameter change in the training approach prevents over-learning and improves the reliability of verification results on new, unseen data
