Softsign - 1 #

Version

name: Softsign (GitHub)
domain: main
since_version: 1
function: True
support_level: SupportType.COMMON
shape inference: True

This version of the operator has been available since version 1.

Summary

Calculates the softsign (x/(1+|x|)) of the given input tensor element-wise.

Inputs

input (heterogeneous) - T: Input tensor

Outputs

output (heterogeneous) - T: The softsign (x/(1+|x|)) values of the input tensor computed element-wise

Type Constraints

T in ( tensor(double), tensor(float), tensor(float16) ): Constrain input and output types to float tensors.

Examples

default

node = onnx.helper.make_node(
    "Softsign",
    inputs=["x"],
    outputs=["y"],
)

x = np.array([-1, 0, 1]).astype(np.float32)
y = np.array([-0.5, 0, 0.5]).astype(np.float32)
expect(node, inputs=[x], outputs=[y], name="test_softsign_example")

x = np.random.randn(3, 4, 5).astype(np.float32)
y = x / (1 + np.abs(x))
expect(node, inputs=[x], outputs=[y], name="test_softsign")
