Data augmentation
=================

These layers perform random transformations over the previous layer.


RandomCrop
----------

.. doxygenfunction:: RandomCrop

Example:

.. code-block:: c++

   l = RandomCrop(l, {20, 20});
   



RandomCropScale
---------------

.. doxygenfunction:: RandomCropScale

Example:

.. code-block:: c++

   l = RandomCropScale(l, {0.9f, 1.0f});
   



RandomCutout
---------------

.. doxygenfunction:: RandomCutout

Example:

.. code-block:: c++

   // The values of x_min, x_max, y_min and y_max should be between 0.0 and 1.0
   l = RandomCutout(l, {0.3, 0.7},{0.3,0.9});
   



RandomFlip
----------

.. doxygenfunction:: RandomFlip

Example:

.. code-block:: c++

   l = RandomFlip(l, 0);




RandomHorizontalFlip
---------------------

.. doxygenfunction:: RandomHorizontalFlip

Example:

.. code-block:: c++

   l = RandomHorizontalFlip(l);
   



RandomRotation
--------------

.. doxygenfunction:: RandomRotation

Example:

.. code-block:: c++

   l = RandomRotation(l, {-20,30});




RandomScale
--------------

.. doxygenfunction::  RandomScale(layer parent, vector<float> factor, string da_mode= "nearest", float constant= 0.0f, string coordinate_transformation_mode="asymmetric", string name= "")

Example:

.. code-block:: c++

   l = RandomScale(l, {0.9,1.1});




RandomShift
--------------

.. doxygenfunction:: RandomShift

Example:

.. code-block:: c++

   // The shift factors must fall within the range [-1.0, 1.0]
   l = RandomShift(l, {-0.3,0.3},{-0.2, 0.2});




RandomVerticalFlip
---------------------

.. doxygenfunction:: RandomVerticalFlip

Example:

.. code-block:: c++

   l = RandomVerticalFlip(l);
