Abstract (요약) 🕵🏻‍♂️

Neural text generation models are often autoregressive language models or seq2seq
models. These models generate text by sampling words sequentially, with each
word conditioned on the previous word, and are state-of-the-art for several machine
translation and summarization benchmarks. These benchmarks are often defined
by validation perplexity even though this is not a direct measure of the quality
of the generated text. Additionally, these models are typically trained via maximum likelihood and teacher forcing. These methods are well-suited to optimizing
perplexity but can result in poor sample quality since generating text requires conditioning on sequences of words that may have never been observed at training time.
We propose to improve sample quality using Generative Adversarial Networks
(GANs), which explicitly train the generator to produce high quality samples and
have shown a lot of success in image generation. GANs were originally designed
to output differentiable values, so discrete language generation is challenging for
them. We claim that validation perplexity alone is not indicative of the quality
of text generated by a model. We introduce an actor-critic conditional GAN that
fills in missing text conditioned on the surrounding context. We show qualitatively and quantitatively, evidence that this produces more realistic conditional and
unconditional text samples compared to a maximum likelihood trained model.
