# falsePositiveCount(of:)

Returns the number of times the predicted label did not match the true label.

## Declaration

```swift
func falsePositiveCount(of label: Label) -> Int
```

## Parameters

- `label`: The label to use as true positive.

## Return Value

Return Value The false positive count.

## Discussion

Discussion If the label does not have a confidence threshold, the false positive count is the number of elements in the ground truth labels collection that do not contain the label. If the label has a confidence threshold NaN, the false positive count is 0. If the label is not in the known set of labels, the false positive count is 0.
