合成数据的预预训练在自然语言训练上的收益有限

一篇新发表在arXiv上的研究论文表明,语言模型的预预训练(PPT)在性能上并不优于传统的自然语言训练。研究发现,即使在自然语言数据稀缺的情况下,在较小的自然语言语料库上重复训练(epoch)也比各种PPT课程(包括k-Dyck和神经元胞自动机)取得了更好的结果。研究还指出,报告的PPT收益对权重初始化敏感,并且模型在后续的自然语言训练中倾向于遗忘在PPT中学到的信息。 AI

影响 表明当前合成预预训练方法可能不是语言模型开发中最有效的计算利用方式。

    重新思考预预训练

    arXiv:2610.40051v1 Announce Type: cross Abstract: We report that allocating compute to synthetic pre-pretraining (PPT) never outperforms pure natural-language training in our compute-matched experiments. This holds across four PPT curricula (k-Dyck, neural cellular automata (NCA)…
