Variance of a tensor, alongside the specified axis.
tf.keras.backend.var(
x, axis=None, keepdims=False
)
x
: A tensor or variable.axis
: An integer, the axis to compute the variance.keepdims
: A boolean, whether to keep the dimensions or not.
If keepdims
is False
, the rank of the tensor is reduced
by 1. If keepdims
is True
,
the reduced dimension is retained with length 1.A tensor with the variance of elements of x
.
