WebMay 22, 2015 · The batch size defines the number of samples that will be propagated through the network. For instance, let's say you have 1050 training samples and you want to set up a batch_size equal to 100. The algorithm takes the first 100 samples (from 1st to 100th) from the training dataset and trains the network. WebSep 14, 2024 · It means label of generated_images for discriminator should be '0' because It is fake. However, Above code is not... Thus, I think labels should be like below labels = np.concatenate([np.zeros((batch_size, 1)), np.one((batch_size, 1))]) If this is wrong, Could you tell me why it is? Thanks :) they them movie netflix
