.. index:: pair: page; HardSwish .. _doxid-dev_guide_op_hardswish: HardSwish ========= General ~~~~~~~ HardSwish operation applies following formula on every element of :math:`\src` tensor (the variable names follow the standard :ref:`Naming Conventions `): .. math:: dst = src * \frac{\min(\max(src + 3, 0), 6)}{6} Operation attributes ~~~~~~~~~~~~~~~~~~~~ HardSwish operation does not support any attribute. Execution arguments ~~~~~~~~~~~~~~~~~~~ The inputs and outputs must be provided according to below index order when constructing an operation. Inputs ------ ====== ============== ===================== Index Argument Name Required or Optional ====== ============== ===================== 0 ``src`` Required ====== ============== ===================== Outputs ------- ====== ============== ===================== Index Argument Name Required or Optional ====== ============== ===================== 0 ``dst`` Required ====== ============== ===================== Supported data types ~~~~~~~~~~~~~~~~~~~~ HardSwish operation supports the following data type combinations. ===== ===== Src Dst ===== ===== f32 f32 bf16 bf16 f16 f16 ===== ===== Implementation Notes ~~~~~~~~~~~~~~~~~~~~ HardSwish supports in-place operations, meaning that ``src`` can be used as both input and output (``dst``). In case of in-place operation, the original ``src`` data will be overwritten. Use in-place operations whenever possible for performance.
