Threshold Analyzer

Go to Product

This node performs threshold analysis for binary classification or retrieval results with confidence values. It allows to calculate Precision, Recall, F1, and Accuracy measures depending on varying confidence/probability values.

Options

Class column
The actual class value assigned to a data item.
Positive class value
The value of the positive class.
Positive class probability
The column providing the numeric probability for an item classified as “positive”.

Input Ports

Icon
Input with actual class values (binary) and probabilities.

Output Ports

Icon
Precision, Recall, F1, and Accuracy values for different thresholds.

Views
