Ask HN: 探讨一下 Transformer 的模拟模型
4 分•作者: JPLeRouzic•5 个月前
（如果这个问题很蠢，请见谅）
大约 80 年前，许多计算机使用模拟逻辑，例如，带有可变电阻的放大器可以进行乘法和除法运算。
矩阵乘法似乎是 Transformer 架构的核心。
我想知道，基于一个大致相似的概念来创建一种 Transformer 是否有意义？
如果你好奇为什么会问这个问题，毕竟现在还有人设计使用电子管甚至机械继电器的数字计算机，那么为什么不能设计模拟 Transformer 呢？

(Sorry if this a stupid question)<p>Roughly 80 years ago many computers used analog logic, for example an amplifier with variable resistors could multiply and divide.<p>The matrix multiplication seems to be central in Transformer architecture.<p>I wonder if it would make sense to create a sort of Transformer on a vaguely similar concept?<p>If you wonder why this question, after all there are still guys who design digital computers with tubes or even mechanical relays, then why not analog Transformers?<p>https://hackaday.com/2023/12/05/a-single-board-computer-with-vacuum-tubes/<p>https://hackaday.io/project/189725-homebrew-16-bit-relay-computer
