Masked Latent Semantic Modeling: an Efficient Pre-training Alternative to Masked Language Modeling (2023.findings-acl)
Copied to clipboard
| Challenge: | a recent study suggests that masked language models are a useful pre-training technique for natural language processing . a study using mlms pre-trained by a team of researchers has improved performance . |
| Approach: | They propose an alternative to the classic masked language modeling paradigm . they use an unsupervised technique which uses sparse coding to make the prediction possible . |
| Outcome: | The proposed technique improves on pre-trained models compared to vanilla MLM . the proposed model returns distributions over their vocabulary peaking at plausible substitutes . |
