- Parameters
-
prop_kind Propagation kind. Possible values are dnnl::prop_kind::backward_data and dnnl::prop_kind::backward (diffs for all parameters are computed in this case). diff_data_desc Diff source and diff destination memory descriptor. data_desc Source memory descriptor. epsilon Batch normalization epsilon parameter. flags Batch normalization flags (dnnl::normalization_flags).
