            Gradient of Image in PyTorch - for Gradient Penalty calculation in WGAN
            Asked 2022-Apr-02 at 17:11

            I am following this Github Repo for the WGAN implementation with Gradient Penalty.

            And I am trying to understand the following method, which does the job of unit-testing the gradient-penalty calulations.

            ...

            ANSWER

            Answered 2022-Apr-02 at 17:11
            For the line

            good_gradient = torch.ones(*image_shape) / torch.sqrt(image_size)

            First, note the Gradient Penalty term in WGAN is =>

            (norm(gradient(interpolated)) - 1)^2

            And for the Ideal Gradient (i.e. a Good Gradient), this Penalty term would be 0. i.e. A Good gradient is one which has its gradient_penalty is as close to 0 as possible

            This means the following should satisfy, after considering the L2-Norm of the Gradient

            (norm(gradient(x')) -1)^2 = 0

            i.e norm(gradient(x')) = 1

            i.e. sqrt(Sum(gradient_i^2) ) = 1

            Now if you just continue simplifying the above (considering how norm is calculated, see my note below) math expression, you will end up with

            good_gradient = torch.ones(*image_shape) / torch.sqrt(image_size)

            Since you are passing the image_shape as (256, 1, 28, 28) - so torch.sqrt(image_size) in your case is tensor(28.)

            Effectively the above line is dividing each element of A 4-D Tensor like [[[[1., 1. ... ]]]] with a scaler tensor(28.)

            Separately, note how norm is calculated

            torch.norm without extra arguments performs, what is called a Frobenius norm which is effectively reshaping the matrix into one long vector and returning the 2-norm of that.

            Given an M * N matrix, The Frobenius Norm of a matrix is defined as the square root of the sum of the squares of the elements of the matrix.

            The problem is that you are using train_ds.take(1) to take exactly one batch from your dataset, which has the BATCH_SIZE = 5. If you want to display 9 images in a 3x3 plot, then simply change your BATCH_SIZE to 9. Alternatively, you can adjust the number of subplots you want to create like this:

            No neurons in the last layer should be same as the number of classes you want to classify (it should be 3 if you are trying to classify 3 types of flowers not 32) . Added a few convolution layers and pooling layers to improve the performance too.
