foldr(
    fn,
    elems,

)

Defined in tensorflow/contrib/keras/python/keras/backend.py.

Reduce elems using fn to combine them from right to left.

Arguments:

fn: Callable that will be called upon each element in elems and an
    accumulator, for instance `lambda acc, x: acc + x`
elems: tensor
initializer: The first value used (`elems[-1]` in case of None)
name: A string name for the foldr node in the graph

Returns:

Same type and shape as initializer
