Switches between two operations depending on a scalar value.
Note that both then_expression and else_expression
should be symbolic tensors of the same shape.
k_switch(condition, then_expression, else_expression)
condition |

then_expression |
either a tensor, or a function that returns a tensor. |
else_expression |
either a tensor, or a function that returns a tensor. |
The selected tensor.
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.
