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.

Section

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().
