Unsupervised Text Embedding Space Generation Using Generative Adversarial Networks for Text Synthesis
Published 2023-10-01“…Because natural language is composed of discrete tokens, a generator has difficulty updating its gradient through backpropagation; therefore, most text-GAN studies generate sentences starting with a random token based on a reward system. Thus, the generators of previous studies are pre-trained in an autoregressive way before adversarial training, causing data memorization that synthesized sentences reproduce the training data. …”
