摘要:
我们提出了三种简单的字节对编码(BPE)随机变体,并探究随机化合并操作的选择是否会显著影响下游机器翻译任务。我们聚焦于向形态丰富语言的翻译,假设该任务可能对子词的选择方法较为敏感。使用贝叶斯线性模型的分析表明,其中两种变体的性能与标准BPE几乎无法区分,而第三种变体的性能下降幅度低于我们的预期。我们得出结论:尽管标准BPE已被广泛使用,但仍存在一系列值得研究的潜在有趣变体。我们的代码可在以下网址获取:https://github.com/bltlab/random-bpe。
英文摘要:
We introduce three simple randomized variants of byte pair encoding (BPE) and explore whether randomizing the selection of merge operations substantially affects a downstream machine translation task. We focus on translation into morphologically rich languages, hypothesizing that this task may show sensitivity to the method of choosing subwords. Analysis using a Bayesian linear model indicates that two of the variants perform nearly indistinguishably compared to standard BPE while the other degrades performance less than we anticipated. We conclude that although standard BPE is widely used, there exists an interesting universe of potential variations on it worth investigating.
