Less

Versioned name : Less-1

Category : Comparison binary

Short description : Less performs element-wise comparison operation with two given tensors applying multi-directional broadcast rules.

Detailed description Before performing arithmetic 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 Less 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 :

    • 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.

Example 1

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

        </port>
    </input>
    <output>
        <port id="2">
