Versioned name: IsFinite-10

Category: Comparison

Short description: IsFinite performs element-wise test for finiteness (not Infinity and not NaN) on elements of a given input tensor. It returns the boolean mask of a given tensor which maps NaN and Infinity to False and all other values to True IsFinite operation has no attributes.

Detailed description: IsFinite returns the boolean mask of the input tensor in which False corresponds to NaN and Infinity and True to all other values.

• The output tensor has the same shape as the input tensor.
• The i'th element of the output tensor is False if i'th element of the input tensor is NaN or Inf. Otherwise, it is True.
• For example, for a given input tensor [NaN, 2.1, 3.7, Inf] the output tensor is [False, True, True, False].

Attributes

IsFinite operation has no attributes.

Inputs

• 1: A tensor of type T and arbitrary shape. Required.

Outputs

• 1: The result of element-wise IsFinite operation. A tensor of type boolean and the same shape as input tensor.

Types

• T: any supported floating-point type.

Examples

.. code-block:: cpp

<layer ... type="IsFinite"> 256 56 256 56

.. code-block:: cpp

<layer ... type="IsFinite"> 4 < !-- Input value is: [NaN, 2.1, 3.7, Inf] --> 4 < !-- Output value is: [False, True, True, False] -->
