Celu - 28¶

Version¶

name: Celu (GitHub)
domain: main
since_version: 28
function: True
support_level: SupportType.COMMON
shape inference: True

This version of the operator has been available since version 28.

Summary¶

Continuously Differentiable Exponential Linear Units: Perform the linear unit element-wise on the input tensor X using formula:

max(0,x) + min(0,alpha*(exp(x/alpha)-1))

Function Body¶

The function definition for this operator.

&lt;
  domain: &#34;&#34;,
  opset_import: [&#34;&#34; : 28]
&gt;
Celu &lt;alpha&gt;(X) =&gt; (Y)
{
   Alpha = Constant &lt;value_float: float = @alpha&gt; ()
   AlphaCast = CastLike (Alpha, X)
   XScaled = Div (X, AlphaCast)
   EluResult = Elu &lt;alpha: float = 1&gt; (XScaled)
   Y = Mul (AlphaCast, EluResult)
}

Attributes¶

alpha - FLOAT (default is 1.0):

The Alpha value in Celu formula which control the shape of the unit. The default value is 1.0.

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.
