Beyond Text Compression: Evaluating Tokenizers Across Scales

ACL 2025long

The choice of tokenizer can profoundly impact language model performance, yet accessible and reliable evaluations of tokenizer quality remain an open challenge. Inspired by scaling consistency, we show that smaller models can accurately predict significant differences in tokenizer impact on larger m…

Learning Language-Specific Layers for Multilingual Machine Translation

ACL 2023long

Multilingual Machine Translation promises to improve translation quality between non-English languages. This is advantageous for several reasons, namely lower latency (no need to translate twice), and reduced error cascades (e.g., avoiding losing gender and formality information when translating thr…

Non-Autoregressive Neural Machine Translation: A Call for Clarity

EMNLP 2022main

Non-autoregressive approaches aim to improve the inference speed of translation models by only requiring a single forward pass to generate the output sequence instead of iteratively producing each predicted token. Consequently, their translation quality still tends to be inferior to their autoregres…
