# BNNS.GradientClipping.byGlobalNorm(threshold:globalNorm:)

A constant that indicates that the operation clips gradients to a specified global Euclidean norm.

## Declaration

```swift
case byGlobalNorm(threshold: Float, globalNorm: Float = 0)
```

## Parameters

- `threshold`: The maximum Euclidean norm.
- `globalNorm`: An optional value for a known global Euclidean norm. Set to 0 to specify that the function computes the norm.
