SpARK: An Embarrassingly Simple Sparse Watermarking in LLMs with Enhanced Text Quality (2026.findings-eacl)
Copied to clipboard
| Challenge: | Existing methods for detecting and monitoring generated text face a trade-off between the quality of the generated text and the effectiveness of the watermarking process. |
| Approach: | They propose a new type of LLM watermark, Sparse WatermARK, which uses watermarks to a small subset of generated tokens distributed across the text. |
| Outcome: | The proposed method outperforms existing methods in detectability and quality while maintaining generated text quality. |
