  1. API - Cost

  2. ==================

  3. 

  4. To make TensorLayer simple, we minimize the number of cost functions as much as

  5. we can. So we encourage you to use TensorFlow's function, , see `TensorFlow API <https://www.tensorflow.org/versions/r2.0/api_docs/python/tf>`_.

  6. 

  7. .. note::

  8.     Please refer to `Getting Started <https://github.com/tensorlayer/tensorlayer/tree/master/docs/user>`_ for getting specific weights for weight regularization.
