Deterministic Non-Autoregressive Neural Sequence Modeling by Iterative Refinement

EMNLP 2018 Jason LeeElman MansimovKyunghyun Cho

We propose a conditional non-autoregressive neural sequence model based on iterative refinement. The proposed model is designed based on the principles of latent variable models and denoising autoencoders, and is generally applicable to any sequence generation task... (read more)
