From characters to words: the turning point of BPE merges (2021.eacl-main)
Copied to clipboard
| Challenge: | morphological complexity is still a major challenge for NLP and the study of language. |
| Approach: | They perform a cross-linguistic comparison following incremental merges of BPE for 47 diverse languages. |
| Outcome: | The results show that language distributions are similar under specific levels of tokenization. |
Interpretability for Morphological Inflection: from Character-level Predictions to Subword-level Rules (2021.eacl-main)
Copied to clipboard
| Challenge: | Neural models for morphological inflection have recently attained very high results, but their interpretation remains challenging. |
| Approach: | They propose a linguistically-motivated variant to the encoder-decoder model with attention that incorporates a character-level cross-attention mechanism and a self-attention module over substrings of the input. |
| Outcome: | The proposed model performs well on three typologically-different languages and is highly interpretable. |
