NotEqual

Versioned name: NotEqual-1

Category: Comparison binary

Short description: NotEqual performs element-wise comparison operation with two given tensors applying multi-directional broadcast rules specified in the auto_broadcast attribute.

Detailed description

Before performing comparison operation, input tensors a and b are broadcasted if their shapes are different. Broadcasting is performed according to auto_broadcast value.

After broadcasting, NotEqual does the following with the input tensors a and b:

\[o_{i} = a_{i} != b_{i}\]

Attributes:

• auto_broadcast

  • Description: specifies rules used for auto-broadcasting of input tensors.

  • Range of values:

    • none - no auto-broadcasting is allowed, all input shapes should match

    • numpy - numpy broadcasting rules, description is available in Broadcast Rules For Elementwise Operations,

    • pdpd - PaddlePaddle-style implicit broadcasting, description is available in Broadcast Rules For Elementwise Operations.

  • Type: string

  • Default value: “numpy”

  • Required: no

Inputs

• 1: A tensor of type T. Required.

• 2: A tensor of type T. Required.

Outputs

• 1: The result of element-wise comparison operation. A tensor of type boolean.

Types

• T: arbitrary supported type.

Examples

Example 1

<layer ... type="NotEqual">
    <input>
        <port id="0">
            <dim>256</dim>
            <dim>56</dim>
        </port>
        <port id="1">
            <dim>256</dim>
            <dim>56</dim>
        </port>
    </input>
    <output>
        <port id="2">
