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 :

    • 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>
