    """1D Minibatch Discrimination Module as proposed in the paper `"Improved Techniques for
    Training GANs by Salimans et. al." <https://arxiv.org/abs/1805.08318>`_

    Allows the Discriminator to easily detect mode collapse by augmenting the activations to the succeeding
    layer with side information that allows it to determine the 'closeness' of the minibatch examples
    with each other

    .. math :: o(x_{i})_b &= \\sum_{j=1}^{n} c_b(x_{i},x_{j}) \\in \\mathbb{R} \\\\
    .. math :: o(x_{i}) &= \\Big[ o(x_{i})_1, o(x_{i})_2, \\dots, o(x_{i})_B \\Big] \\in \\mathbb{R}^B \\\\
    .. math :: o(X) \\in \\mathbb{R}^{n \\times B}

    This is followed by concatenating :math:`o(x_{i})` and :math:`f(x_{i})`

    where

    - :math:`f(x_{i}) \\in \\mathbb{R}^A` : Activations from an intermediate layer
    - :math:`f(x_{i}) \\in \\mathbb{R}^A` : Parameter Tensor for generating minibatch discrimination matrix


    Args:

        out_features (int): Number of output features that are to be concatenated corresponding to dimension :math:`B`
        intermediate_features (int): Intermediate number of features corresponding to dimension :math:`C`
