Kinds of propagation.

Enum Values
-----------

.. index:: pair: enumvalue; dnnl_prop_kind_undef
.. _doxid-group__dnnl__api__primitives__common_1ggae3c1f22ae55645782923fbfd8b07d0c4a68c8ec51f34458261cac7d12eee01372:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dnnl_prop_kind_undef

Undefined propagation type.

.. index:: pair: enumvalue; dnnl_forward_training
.. _doxid-group__dnnl__api__primitives__common_1ggae3c1f22ae55645782923fbfd8b07d0c4a992e03bebfe623ac876b3636333bbce0:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dnnl_forward_training

Forward data propagation (training mode).

In this mode primitives perform computations necessary for subsequent backward propagation.

.. index:: pair: enumvalue; dnnl_forward_inference
.. _doxid-group__dnnl__api__primitives__common_1ggae3c1f22ae55645782923fbfd8b07d0c4a2f77a568a675dec649eb0450c997856d:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dnnl_forward_inference

Forward data propagation (inference mode).

In this mode primitives perform only computations that are necessary for inference and omit computations that are necessary only for backward propagation.

.. index:: pair: enumvalue; dnnl_forward
.. _doxid-group__dnnl__api__primitives__common_1ggae3c1f22ae55645782923fbfd8b07d0c4a6a59d07a8414bb69b3cb9904ed302adb:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dnnl_forward

Forward data propagation (alias for ``dnnl_forward_training``).

.. index:: pair: enumvalue; dnnl_backward
.. _doxid-group__dnnl__api__primitives__common_1ggae3c1f22ae55645782923fbfd8b07d0c4a326a5e31769302972e7bded555e1cc10:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dnnl_backward

Backward propagation (with respect to all parameters).
