Residual Energy-Based Models for Text Generation

Deng, Yuntian, Bakhtin, Anton, Ott, Myle et al.

Understand

Text generation is ubiquitous in many NLP tasks, from summarization, to dialogue and machine translation.

  • The dominant parametric approach is based on locally normalized models which predict one word at a time.
  • While these work remarkably well, they are plagued by exposure bias due to the greedy nature of the generation process.
  • In this work, we investigate un-normalized energy-based models (EBMs) which operate not at the token but at the sequence level.
