I am trying to use DCGAN for the waterbirds dataset with the following hyperparameters, but I am getting low-contrast images. It would be great if anyone has any suggestions as to what could be some usual reasons for such an outcome.
LEARNING_RATE = 2e-4
BATCH_SIZE = 64
IMAGE_SIZE = 64
CHANNELS_IMG = 3
NOISE_DIM = 150
NUM_EPOCHS = 150
