For both MSCOCO and Quora datasets, we randomly sample 100 sentence pairs (original sentence, paraphrased sentence) from the test corpus, and apply the generative architectures, including both the VAE * model and our GAP model, to generating paraphrases.
we obtain three different sentence pairs: (original sentence, "generated" sentence) by the reference, (original sentence, generated paraphrase) by VAE * , and by our GAP model.
