# Tolerances in the Deep Learning Tools

Each of the VisionPro Deep Learning tools have a tolerance that can be adjusted, which allows the tool to be "picky" in its predictions.

| Blue Read Tool | Blue Locate Tool | Green Classify Tool | Red Analyze Tool
--- | --- | --- | --- | ---
Where to adjust | Feature location Feature score Match data | Feature location Feature score Match data | Match scores | Defect area Score
What's being adjusted | Feature Score | Feature Score | Class Score | Defect Probability

In addition, you can adjust each tool's Threshold parameter (which is one of the ).

Changing the Threshold parameter affects Recall and Precision in the following ways:

Threshold | Recall | Precision
--- | --- | ---
Lowering the Threshold | Increases | Decreases
Increasing the Threshold | Decreases | Increases

Changing the Threshold parameter affects False Positives and False Negatives in the following ways:

Threshold | False Positives | False Negatives
--- | --- | ---
Lowering the Threshold | Decreases | Increases
Increasing the Threshold | Increases | Decreases
