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

.. index:: pair: enumvalue; undef
.. _doxid-group__dnnl__api__attributes_1ggac7db48f6583aa9903e54c2a39d65438faf31ee5e3824f1f5e5d206bdf3029f22b:

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

	undef

Undefined propagation kind.

.. index:: pair: enumvalue; forward_training
.. _doxid-group__dnnl__api__attributes_1ggac7db48f6583aa9903e54c2a39d65438fa24775787fab8f13aa4809e1ce8f82aeb:

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

	forward_training

Forward data propagation (training mode).

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

.. index:: pair: enumvalue; forward_inference
.. _doxid-group__dnnl__api__attributes_1ggac7db48f6583aa9903e54c2a39d65438fa3b9fad4f80d45368f856b5403198ac4c:

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

	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.
