tf.keras.ops.elu

Exponential Linear Unit activation function.

tf.keras.ops.elu(
    x, alpha=1.0
)

It is defined as:

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

x Input tensor.
alpha A scalar, slope of positive section. Defaults to 1.0.

A tensor with the same shape as x.

Example:

x = np.array([-1., 0., 1.])
x_elu = keras.ops.elu(x)
print(x_elu)
array([-0.63212055, 0., 1.], shape=(3,), dtype=float64)
