tf.keras.backend.var( x, axis=None, keepdims=False )
Defined in tensorflow/python/keras/_impl/keras/backend.py
.
Variance of a tensor, alongside the specified axis.
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
