# BNNS.GradientClipping Constants that describe clipping functions. ``` enum GradientClipping ``` ## Topics ### Gradient Clipping Functions [`case none`](/documentation/Accelerate/BNNS/GradientClipping/none) A constant that indicates that the operation doesn’t clip gradients. [`case byValue(bounds: ClosedRange)`](/documentation/Accelerate/BNNS/GradientClipping/byValue(bounds:)) A constant that indicates that the operation clips gradients to a specified range. [`case byNorm(threshold: Float)`](/documentation/Accelerate/BNNS/GradientClipping/byNorm(threshold:)) A constant that indicates that the operation clips gradients to a specified Euclidean norm. [`case byGlobalNorm(threshold: Float, globalNorm: Float)`](/documentation/Accelerate/BNNS/GradientClipping/byGlobalNorm(threshold:globalNorm:)) A constant that indicates that the operation clips gradients to a specified global Euclidean norm. --- Copyright © 2026 Apple Inc.
