摘要

reinerpope发布新黑板讲座，从逻辑门开始讲解AI训练和推理的构建过程，并手工演示4位乘累加操作，指出该操作是训练中矩阵乘法的基础。

客观事实
  • reinerpope发布黑板讲座视频，讲解AI训练和推理如何从逻辑门构建
  • 手工演示4位乘累加，作为训练中矩阵乘法的基础操作

原文

.@reinerpope's new blackboard lecture goes all the way down: how AI training and inference are built up from logic gates on silicon.

He walks me through a 4-bit multiply-accumulate by hand, and shows how that primitive is the foundation for the matrix multiplies in training runs.
