Misclassification Visualization Using Similar Sample Overlays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for visualizing the prediction basis of machine learning models, such as Grad-CAM, require complex processing and only partially indicate the prediction bases, making it unclear how to improve the model when incorrect predictions occur.
Innovation Solution
A learning process visualization system that searches for samples with similar features to misclassified samples and displays superimposed images to highlight similarities between misclassified and extracted samples, facilitating model improvement.

Engineering Contradiction Analysis
1Loss of information
If complex processing is used to indicate prediction bases (e.g., Grad-CAM), then the prediction basis can be visualized, but the processing becomes complex and only partial understanding is achieved
Solution Approach 1:
The patent extracts and displays only the necessary visual information for understanding misclassification by comparing the misclassified sample with similar samples. Instead of using complex global visualization methods, it selectively extracts and presents the specific visual features that lead to incorrect predictions, thereby reducing processing complexity while maintaining informative value.
Solution Approach 2:
The patent segments the visualization task into two clear parts: displaying the misclassified sample and displaying similar samples with their similarity information. This segmentation allows the system to present prediction basis information in a structured, easier-to-process manner rather than using a single complex visualization method.
2Reliability
If only prediction basis for incorrect prediction is indicated, then focus is on errors, but understanding remains incomplete and improvement measures are unclear
Solution Approach 1:
The patent provides feedback by displaying similar samples alongside the misclassified sample, showing what features the model actually perceived as similar. This feedback mechanism reveals not only where the model erred but also what visual features it relied upon, providing clear guidance on how to improve the model's decision boundaries and classification accuracy.
3Loss of information
If existing visualization techniques are used, then prediction basis can be shown, but clear suggestions for model improvement cannot be obtained
Solution Approach 1:
The patent applies local quality by focusing the visualization on specific aspects that matter for misclassification analysis - namely, the visual features of the misclassified sample and the visual features of similar samples. This localized approach provides clear, actionable insights into model errors without the noise of irrelevant information, making it easier to derive improvement suggestions.
