The layer transforms the input data into zero mean and unit variance and then scales and shifts the data by parameters, gamma and beta respectively. These parameters are learnt by the network. If deterministic is false (training), the mean and variance over the batch is calculated and the data is normalized. If it is set to true (testing) then the mean and variance accrued over the training set is used.
