clamp

An activation function that returns its input clamped to a specified range.

Declaration

static var clamp: BNNSActivationFunction { get }

This constant defines an activation function that returns values using the following operation:

min(max(x, alpha), beta)

Use alpha and beta to specify the clamping range:

var activation = BNNSActivation(function: .clamp, 
                                alpha: -5, 
                                beta: 5)

The following illustrates the output that the activation function generates from inputs in the range -10...10:
