AI理论论文表明Transformer在奇偶性任务上至少需要两层

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员证明，两层Transformer模型是计算PARITY任务（确定二进制序列中1的数量是偶数还是奇数）所需的最低层数。他们证明，单层Transformer由于其平均敏感性增长慢于PARITY，因此无法解决该问题。此外，一种新的构造表明，PARITY可以通过四层Transformer计算，而无需长度依赖的位置编码或hardmax等不切实际的假设，并且与因果掩码兼容。 AI

影响 为Transformer架构的计算能力和局限性提供了理论见解。

    奇偶性、敏感性和Transformers

    arXiv:2602.05896v2 Announce Type: replace Abstract: Understanding what neural architectures can and cannot compute is a central challenge in the theory of AI. One of the fundamental problems in this context is the PARITY task, which asks whether the number of 1s in a binary input…
