Papers with autoregressive baseline
Align-Refine: Non-Autoregressive Speech Recognition via Iterative Realignment (2021.naacl-main)
Copied to clipboard
| Challenge: | Non-autoregressive encoder-decoder models improve decoding speed, but generation quality suffers . editing at the level of output sequences limits model flexibility. |
| Approach: | They propose *iterative realignment* which iteratively realigns connectionist temporal alignments. |
| Outcome: | The proposed model matches an autoregressive baseline with a 14x speedup on the WSJ dataset; on LibriSpeech, it achieves an LM-free test-other WER of 9.0% (19% relative improvement on comparable work). |
Releasing the Capacity of GANs in Non-Autoregressive Image Captioning (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing non-autoregressive (NAR) models suffer from their inherent multi-modality problem. |
| Approach: | They propose an Adversarial Non-autoregressive Transformer for Image Captioning that improves model performance by modifying model structure to be compatible with contrastive learning. |
| Outcome: | The proposed model achieves 26.72 times faster than the autoregressive model on the MSCOCO dataset. |
