Byte-Based vs. Subword Tokenization in Zero-Shot Cross-Lingual Transfer on XTREME

This report synthesises findings from 11 peer-reviewed papers addressing the following research question: How does byte-based tokenization compare to subword tokenization in terms of zero-shot cross-lingual transfer accuracy on the XTREME benchmark when trained on varying corpus sizes. 6 claims were extracted from source literature; 6 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.5/10. This report is a machine-generated literature synthesis and does not constitute original research.
