LogicalOr¶

Versioned name: LogicalOr-1

Category: Logical binary

Short description: LogicalOr performs element-wise logical OR operation with two given tensors applying multi-directional broadcast rules.

Detailed description: Before performing logical operation, input tensors a and b are broadcasted if their shapes are different and auto_broadcast attributes is not none. Broadcasting is performed according to auto_broadcast value.

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

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

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 must 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_BOOL and arbitrary shape. Required.
2: A tensor of type T_BOOL and arbitrary shape. Required.

Outputs

1: The result of element-wise LogicalOr operation. A tensor of type T_BOOL and the same shape equal to broadcasted shape of two inputs.

Types

T_BOOL: boolean.

Examples

Example 1: no broadcast

<layer ... type="LogicalOr">
    <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">
            <dim>256</dim>
            <dim>56</dim>
        </port>
    </output>
</layer>

Example 2: numpy broadcast

<layer ... type="LogicalOr">
    <input>
        <port id="0">
            <dim>8</dim>
            <dim>1</dim>
            <dim>6</dim>
            <dim>1</dim>
        </port>
        <port id="1">
            <dim>7</dim>
            <dim>1</dim>
            <dim>5</dim>
        </port>
    </input>
    <output>
        <port id="2">
            <dim>8</dim>
            <dim>7</dim>
            <dim>6</dim>
            <dim>5</dim>
        </port>
    </output>
</layer>
