LeakyRelu

LeakyRelu - 16

Version

• name: LeakyRelu (GitHub)

• domain: main

• since_version: 16

• function: False

• support_level: SupportType.COMMON

• shape inference: True

This version of the operator has been available since version 16.

Summary

LeakyRelu takes input data (Tensor<T>) and an argument alpha, and produces one output data (Tensor<T>) where the function f(x) = alpha * x for x < 0, f(x) = x for x >= 0, is applied to the data tensor elementwise.

History - Version 16 adds bfloat16 to the types allowed.

Attributes

• alpha: Coefficient of leakage. Default value is 0.009999999776482582.

Inputs

• X (heterogeneous) - T: Input tensor

Outputs

• Y (heterogeneous) - T: Output tensor

Type Constraints

• T in ( tensor(bfloat16), tensor(double), tensor(float), tensor(float16) ): Constrain input and output types to float tensors.

Examples

leakyrelu_default

default_alpha = 0.01
node = onnx.helper.make_node(
    'LeakyRelu',
    inputs=['x'],
    outputs=['y'],
)
x = np.random.randn(3, 4, 5).astype(np.float32)
y = np.clip(x, 0, np.inf) + np.clip(x, -np.inf, 0) * default_alpha
expect(node, inputs=[x], outputs=[y],
