    Layer Normalization stabilises the training of deep neural networks by
    normalising the outputs of neurons from a particular layer. It computes:

    output = (gamma * (tensor - mean) / (std + eps)) + beta

    Parameters
    ----------
    dimension : ``int``, required.
        The dimension of the layer output to normalize.
    eps : ``float``, optional, (default = 1e-6)
        An epsilon to prevent dividing by zero in the case
        the layer has zero variance.

    Returns
    -------
    The normalized layer output.
