|
**Versioned name**: *SquaredDifference-1*
|
|
|
|
**Category**: *Arithmetic binary*
|
|
|
|
**Short description**: *SquaredDifference* performs element-wise subtract and square the result operation with two given tensors applying broadcasting rule specified in the *auto_broadcast* attribute.
|
|
|
|
**Detailed description**
|
|
As a first step input tensors *a* and *b* are broadcasted if their shapes differ. Broadcasting is performed according to `auto_broadcast` attribute specification. As a second step *Substract* and *Square* the result operation is computed element-wise on the input tensors *a* and *b* according to the formula below:
|
|
|
|
.. math::
|
|
|
|
o_{i} = (a_{i} - b_{i})^2
|
|
|
|
|
|
**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 must match
|
|
* *numpy* - numpy broadcasting rules, description is available in :doc:`Broadcast Rules For Elementwise Operations <openvino_docs_ops_broadcast_rules>`
|
|
* **Type**: string
|
|
* **Default value**: "numpy"
|
|
* **Required**: *no*
|
|
|
|
**Inputs**
|
|
|
|
* **1**: A tensor of type *T* and arbitrary shape. **Required.**
|
|
* **2**: A tensor of type *T* and arbitrary shape. **Required.**
|
|
|
|
**Outputs**
|
|
|
|
* **1**: The result of element-wise subtract and square the result operation. A tensor of type *T* with shape equal to broadcasted shape of two inputs.
|
|
|
|
**Types**
|
|
|
|
* *T*: any numeric type.
|
|
|
|
**Examples**

*Example 1 - no broadcasting*
