ml_ANN_MLP_ActivationFunctions

mlclassOpenCV 5.0.0
import { ml_ANN_MLP_ActivationFunctions } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSConstructor or factory
CLASSml_ANN_MLP_ActivationFunctions
RETURN TYPEOwned native handle
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Native object: release it with using or delete(). Factories can return null; check before calling methods.

possible activation functions

Upstream declaration ↗

Constructors and members

static IDENTITY

Identity function: f(x)=x

IDENTITY: ml_ANN_MLP_ActivationFunctionsValue<0>,

Upstream declaration ↗

static SIGMOID_SYM

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

Note: 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].

SIGMOID_SYM: ml_ANN_MLP_ActivationFunctionsValue<1>,

Upstream declaration ↗

static GAUSSIAN

Gaussian function: f(x)=\beta e^{-\alpha x*x}

GAUSSIAN: ml_ANN_MLP_ActivationFunctionsValue<2>,

Upstream declaration ↗

static RELU

ReLU function: f(x)=max(0,x)

RELU: ml_ANN_MLP_ActivationFunctionsValue<3>,

Upstream declaration ↗

static LEAKYRELU

Leaky ReLU function: for x>0 f(x)=x and x<=0 f(x)=\alpha x 

LEAKYRELU: ml_ANN_MLP_ActivationFunctionsValue<4>
