WebSep 1, 2024 · Unconditional GAN for Fashion-MNIST. In this section, we will develop an unconditional GAN for the Fashion-MNIST dataset. The first step is to define the models. The discriminator model takes as input one 28×28 grayscale image and outputs a binary prediction as to whether the image is real (class=1) or fake (class=0). WebMar 26, 2024 · CTGAN model. The conditional generator can generate synthetic rows conditioned on one of the discrete columns. With training-by-sampling, the cond and training data are sampled according to the log-frequency of each category, thus CTGAN can evenly explore all possible discrete values.
