From Where Words Come: Efficient Regularization of Code Tokenizers Through Source Attribution (2026.acl-long)
Copied to clipboard
| Challenge: | Currently, subword tokenization is the most common approach for vocabulary building in large models. |
| Approach: | They propose to regularize training and minimize overfitting by using source-attributed BPE . they find that undertrained tokens are prone to producing unused, unusable tokens . |
| Outcome: | The proposed techniques reduce the number of under-trained tokens while maintaining the same inference procedure as with regular BPE. |
