.. index:: pair: page; SquaredDifference .. _doxid-dev_guide_op_squareddifference: SquaredDifference ================= General ~~~~~~~ SquaredDifference operation performs element-wise subtraction operation with two given tensors applying multi-directional broadcast rules, after that each result of the subtraction is squared. Before performing arithmetic operation, :math:`src_0` and :math:`src_1` are broadcasted if their shapes are different and ``auto_broadcast`` attributes is not ``none``. Broadcasting is performed according to ``auto_broadcast`` value. After broadcasting SquaredDifference does the following with the input tensors: .. math:: dst_i = (src\_0_i - src\_1_i)^2 Operation attributes ~~~~~~~~~~~~~~~~~~~~ =========================================================================================================================== ============================================================= =========== =============================== ===================== Attribute Name Description Value Type Supported Values Required or Optional =========================================================================================================================== ============================================================= =========== =============================== ===================== :ref:`auto_broadcast ` Specifies rules used for auto-broadcasting of input tensors. string ``none`` , ``numpy`` (default) Optional =========================================================================================================================== ============================================================= =========== =============================== ===================== Execution arguments ~~~~~~~~~~~~~~~~~~~ The inputs and outputs must be provided according to below index order when constructing an operation.
