循环 Transformer:缩放研究中全反向传播优于截断

一篇新发表在 arXiv 上的研究论文探讨了在训练循环 Transformer 中截断反向传播(BPTT)的有效性。Xuyuan Xiong 进行的研究表明,虽然截断可以节省计算资源,但在优化循环次数的情况下,全 BPTT 通常能获得更好的结果。研究发现,循环次数较少且使用全 BPTT 的模型,其性能始终优于计算量相同的截断设置。当模型规模也灵活调整时,最优配置涉及两个完全训练的循环,与非循环模型相比,在参数更少且训练计算量仅略微增加的情况下,实现了更低的验证损失。 AI

影响 这项研究为优化 Transformer 模型的训练计算量提供了见解,可能有助于更高效地开发大型语言模型。
