A benchmark of four generative models for UK windstorm fields finds diffusion-GAN best matches storm statistics but overestimates extremes, while U-net diffusion underestimates them.
LeakyReLU activations are used after convolutional layers in both networks, which return small values for negative inputs instead of zeros in the ReLU activation functions
