Descriptor for a batch normalization backward propagation primitive.

Construction

desc(
    prop_kind aprop_kind,
    const memory::desc& diff_data_desc,
    const memory::desc& data_desc,
    float epsilon,
    normalization_flags flags
    )

Constructs a batch normalization descriptor for backward propagation.

Parameters:

aprop_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).
