k_var {keras}

Variance of a tensor, alongside the specified axis.

Description

Variance of a tensor, alongside the specified axis.

Usage

k_var(x, axis = NULL, keepdims = FALSE)

Arguments

x

A tensor or variable.

axis

An integer, the axis to compute the variance over (axis indexes are 1-based).

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.

Value

A tensor with the variance of elements of x.

Keras Backend

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.).
