Standard deviation of a tensor, alongside the specified axis.
k_std(x, axis = NULL, keepdims = FALSE)
A tensor with the standard deviation of elements of x
.
A tensor or variable.
An integer, the axis to compute the standard deviation over (axis indexes are 1-based).
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.
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.).
