Selects <code>x</code> in test phase, and <code>alt</code> otherwise.
Note that alt should have the same shape as x.
k_in_test_phase(x, alt, training = NULL)Arguments
| x | What to return in test phase (tensor or function that returns a tensor). |
| alt | What to return otherwise (tensor or function that returns a tensor). |
| training | Optional scalar tensor (or R logical or integer) specifying the learning phase. |
Value
Either x or alt based on k_learning_phase().
Keras Backend
This function is part of a set of Keras backend functions that enable lower level access to the core operations of the backend tensor engine (e.g. TensorFlow, CNTK, Theano, etc.).
