Short answer
How can I find my model's false positives and negatives?
Your AI builds a confusion matrix from your prediction data. This shows you exactly which classes are being misidentified. You'll see the specific counts for every error.
Where errors land.
Error breakdown.
The AI categorizes every misclassification so you can see where the model fails.
FP
False Positive counts
The AI identifies where your model claimed a hit that wasn't there. You get a clear list of these specific errors.
FN
False Negative counts
The AI finds where your model missed a real target. This shows you what your model is currently blind to.
ACC
Accuracy breakdown
The AI calculates the overall correctness across all classes. You see how much of the total data was actually right.
HUMAN
Manual review needed
The AI flags high-confusion pairs. You decide which specific edge cases require a human to re-label the data.
The workflow
What your AI does when prediction data arrives.
The AI takes raw labels and predictions to turn them into error reports.
Data ingestion
Your AI reads the ground truth and the predicted labels from your provided dataset.
calculate_confusion_matrixMatrix generation
The AI runs the math to map every prediction against the actual outcome.
calculate_confusion_matrixError isolation
The AI pulls out the specific cells representing false positives and false negatives.
calculate_confusion_matrixPattern detection
Your AI looks for specific classes that are frequently swapped, helping you find systemic biases.

}Calculate a confusion matrix using the data in my 'predictions_v1.csv' file.
Show me the false positives for the 'cat' class in my recent model output.
Analyze the confusion matrix from my 'test_results.json' and tell me which classes are most confused.
Based on the confusion matrix for my 'image_labels.csv', what are my biggest false negative risks?

How this task behaves.
- 01
Can the AI fix my model's errors?
No. The AI only identifies and reports the errors. You have to retrain or adjust your model yourself.
- 02
Does the AI change my original prediction files?
No. The AI only reads your data to perform calculations. It never modifies your source files.
- 03
Can I use this with any dataset?
Yes, as long as your data contains clear ground truth labels and predicted labels for the AI to compare.
- 04
Will the AI automatically re-label my data?
No. The AI identifies where the errors are, but it does not perform any data labeling or cleaning.
- 05
Can it handle multi-class classification?
Yes. The tool is designed to handle multiple classes and show how they interact in the matrix.
