ANN_MLPAnnMlpActivationFunctionSigmoidSym Field

http://www.emgu.com

Symmetrical sigmoid: f(x)=beta*(1-e^{-alpha x})/(1+e^{-alpha x})

Namespace: Emgu.CV.ML
Assembly: Emgu.CV.World.NetStandard (in Emgu.CV.World.NetStandard.dll) Version: 1.0.0

Syntax

public const ANN_MLPAnnMlpActivationFunction SigmoidSym = 1

Public Const SigmoidSym As ANN_MLPAnnMlpActivationFunction = 1

public:
literal ANN_MLPAnnMlpActivationFunction^ SigmoidSym = 1

static val mutable SigmoidSym: ANN_MLPAnnMlpActivationFunction

Field Value

Type: ANN_MLPAnnMlpActivationFunction

Remarks

If you are using the default sigmoid activation function with the default parameter values fparam1 = 0 and fparam2 = 0 then the function used is y = 1.7159 * tanh(2/3 * x), so the output will range from[-1.7159, 1.7159], instead of[0, 1].
