Applies batch normalization on x given mean, var, beta and gamma.

i.e. returns output <- (x - mean) / (sqrt(var) + epsilon) * gamma + beta

k_batch_normalization(x, mean, var, beta, gamma, axis = -1,
  epsilon = 0.001)

Arguments

x

Input tensor or variable.

mean

Mean of batch.

var

Variance of batch.

beta

Tensor with which to center the input.

gamma

Tensor by which to scale the input.

axis

Axis (axis indexes are 1-based). Pass -1 (the default) to select the last axis.

epsilon

Fuzz factor.

Value

A tensor.

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.).
