Constructs an LSTM (with or without peephole and with or without projection) descriptor for backward propagation using \p prop_kind, \p direction, and memory descriptors. The following arguments may point to a zero memory descriptor: - \p src_iter_desc together with \p src_iter_c_desc, \p diff_src_iter_desc, and \p diff_src_iter_c_desc, - \p weights_peephole_desc together with \p diff_weights_peephole_desc - \p bias_desc together with \p diff_bias_desc, - \p dst_iter_desc together with \p dst_iter_c_desc, \p diff_dst_iter_desc, and \p diff_dst_iter_c_desc. This would then indicate that the LSTM backward propagation primitive should not use them and should default to zero values instead. The \p weights_projection_desc together with \p diff_weights_projection_desc may point to a zero memory descriptor. This would then indicate that the LSTM doesn't have recurrent projection layer. \note All memory descriptors can be initialized with #dnnl::memory::format_tag::any value of \p format_tag. Inputs: - src_layer (#dnnl::primitive_desc_base::src_desc (0)) - src_iter (#dnnl::primitive_desc_base::src_desc (1)), if used - src_iter_c (#dnnl::primitive_desc_base::src_desc (2)), if used - weights_layer (#dnnl::primitive_desc_base::weights_desc (0)) - weights_iter (#dnnl::primitive_desc_base::weights_desc (1)) - weights_peephole (#dnnl::primitive_desc_base::weights_desc (2)), if used - weights_projection (#dnnl::primitive_desc_base::weights_desc (index)), if used and index is: - 2, if there is no weights_peephole - 3, otherwise - bias (#dnnl::primitive_desc_base::weights_desc (index)), if used and index is: - 2, if neither weights_peephole nor weights_projection is used - 3, if one of weights_peephole or weights_projection is used - 4, if both weights_peephole and weights_projection are used - dst_layer (#dnnl::primitive_desc_base::dst_desc (0)) - dst_iter (#dnnl::primitive_desc_base::dst_desc (1)), if used - dst_iter_c (#dnnl::primitive_desc_base::dst_desc (2)), if used - diff_dst_layer (#dnnl::primitive_desc_base::diff_dst_desc (0)) - diff_dst_iter (#dnnl::primitive_desc_base::diff_dst_desc (1)), if used - diff_dst_iter_c (#dnnl::primitive_desc_base::diff_dst_desc (2)), if used - workspace (#dnnl::primitive_desc_base::workspace_desc (0)) Outputs: - diff_src_layer (#dnnl::primitive_desc_base::diff_src_desc (0)) - diff_src_iter (#dnnl::primitive_desc_base::diff_src_desc (1)), if used - diff_src_iter_c (#dnnl::primitive_desc_base::diff_src_desc (2)), if used - diff_weights_layer (#dnnl::primitive_desc_base::diff_weights_desc (0)) - diff_weights_iter (#dnnl::primitive_desc_base::diff_weights_desc (1)) - diff_weights_peephole (#dnnl::primitive_desc_base::diff_weights_desc (2)), if used - diff_weights_projection (#dnnl::primitive_desc_base::diff_weights_desc (index)), if used and index is: - 2, if there is no diff_weights_peephole - 3, otherwise - diff_bias (#dnnl::primitive_desc_base::diff_weights_desc (index)), if used and index is: - 2, if neither diff_weights_peephole nor diff_weights_projection is used - 3, if one of diff_weights_peephole or diff_weights_projection is used - 4, if both diff_weights_peephole and diff_weights_projection are used

Constructs an LSTM (with or without peephole) descriptor for backward propagation using \p prop_kind, \p direction, and memory descriptors. The following arguments may point to a zero memory descriptor: - \p src_iter_desc together with \p src_iter_c_desc, \p diff_src_iter_desc, and \p diff_src_iter_c_desc, - \p weights_peephole_desc together with \p diff_weights_peephole_desc - \p bias_desc together with \p diff_bias_desc, - \p dst_iter_desc together with \p dst_iter_c_desc, \p diff_dst_iter_desc, and \p diff_dst_iter_c_desc. This would then indicate that the LSTM backward propagation primitive should not use them and should default to zero values instead. \note All memory descriptors may be initialized with #dnnl::memory::format_tag::any value of \p format_tag.
