k_in_train_phase
Selects x in train phase, and alt otherwise.
Description
Note that alt should have the same shape as x.
Usage
k_in_train_phase(x, alt, training = NULL) Arguments
| Arguments | Description |
|---|---|
| x | What to return in train 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. |

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.). You can see a list of all available backend functions here: https://keras.rstudio.com/articles/backend.html#backend-functions.
Value
Either x or alt based on the training flag. the training flag defaults to k_learning_phase().
