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:
\f[ o_{i} = a_{i} < b_{i} \f]
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.
