layer_activation_elu {keras3}

Applies an Exponential Linear Unit function to an output.

Description

Formula:

f(x) = alpha * (exp(x) - 1.) for x < 0
f(x) = x for x >= 0

Usage

layer_activation_elu(object, alpha = 1, ...)

Arguments

object

Object to compose the layer with. A tensor, array, or sequential model.

alpha

float, slope of negative section. Defaults to 1.0.

...

Base layer keyword arguments, such as name and dtype.

Value

The return value depends on the value provided for the first argument. If object is:

• a keras_model_sequential(), then the layer is added to the sequential model (which is modified in place). To enable piping, the sequential model is also returned, invisibly.

• a keras_input(), then the output tensor from calling layer(input) is returned.

• NULL or missing, then a Layer instance is returned.
