            GANs output is not optimum

            Actually, your generator looks quite simple. Try adding some more convolutional layers Conv2D after upsampling the inputs. There are also many techniques & architectures (such as Pix2Pix) that handle very well high quality images.

            This repository contains quite a few GANs that might help you improve your model + some tricks You can do to improve the overall quality: https://github.com/kochlisGit/Keras-GAN

            PyTorch preserving gradient using external libraries
            Asked 2021-Jun-03 at 18:49

            I have a GAN that returns a predicted torch.tensor. To guide this network, I have a loss function which is a summation of binary cross entropy loss (BCELoss) and Wasserstein distance. However, in order to calculate Wasserstein distance, I am using scipy.stats.wasserstein_distance function from SciPy library. As you might know, this function requires two NumPy arrays as input. So, to use this function, I am converting my predicted tensor and ground-truth tensor to NumPy arrays as follows

            Answered 2021-Jun-03 at 18:49

            Adding an object that is not a tensor that requires_grad to your loss is essentially adding a constant. The derivative of a constant is zero, so this added term is not doing anything to your network's weights.

            tl;dr: You need to rewrite the loss computation in pytorch (or just find an existing implementation, there's numerous on the internets).

            How to transform Ultrasound images for simulation of CT images?
            Asked 2021-May-25 at 21:51

            so I'd like to simulate CT images from ultrasound images using GAN and I am currently working on the data preparation.

            By nature of the ultrasound these images are stored in a cone shaped kind of form:

            I belief it is easier to simulate the CT image that way.

            The homography idea didn't work so this won't serve as an answer, but hopefully some of this is still helpful.

            I basically targeted six keypoints and tried to rectify them. However, the homography didn't handle the cylindrical curve at the top and bottom.

            Pytorch GAN model doesn't train: matrix multiplication error
            Asked 2021-Apr-18 at 14:32

            I'm trying to build a basic GAN to familiarise myself with Pytorch. I have some (limited) experience with Keras, but since I'm bound to do a larger project in Pytorch, I wanted to explore first using 'basic' networks.

            I'm using Pytorch Lightning. I think I've added all necessary components. I tried passing some noise through the generator and the discriminator separately, and I think the output has the expected shape. Nonetheless, I get a runtime error when I try to train the GAN (full traceback below):

            RuntimeError: mat1 and mat2 shapes cannot be multiplied (7x9 and 25x1)

            I noticed that 7 is the size of the batch (by printing out the batch dimensions), even though I specified batch_size to be 64. Other than that, quite honestly, I don't know where to begin: the error traceback doesn't help me.

            Chances are, I made multiple mistakes. However, I'm hoping some of you will be able to spot the current error from the code, since the multiplication error seems to point towards a dimensionality problem somewhere. Here's the code.
