Tiny Chinese BERT models show MLM outperforms MacBERT, research finds

By PulseAugur Editorial · [1 sources] ·

A new research paper explores the effectiveness of different pretraining strategies for small-scale Chinese BERT models. The study compared Masked Language Modeling (MLM), Whole Word Masking (WWM), and MacBERT on a 8.7M parameter model using Chinese Wikipedia data. Results indicate that at this tiny scale, MLM performs best overall, while WWM shows improvements in perplexity and MLM hit rate. The paper also highlights a critical evaluation pitfall where MacBERT's low training loss does not correlate with its high perplexity, suggesting training loss alone is an unreliable metric for mixed replacement strategies.

    Tiny-Scale Chinese BERT Pretraining: A Controlled Comparison of MLM, WWM, and MacBERT Strategies

    arXiv:2610.08879v1 Announce Type: new Abstract: Pretraining strategies significantly impact the quality of language models, yet existing comparisons of Masked Language Modeling (MLM), Whole Word Masking (WWM), and MacBERT-style replacement have focused primarily on base-scale mod…
