神经网络：令牌ID如何变成矩阵乘法

作者 PulseAugur 编辑部 · [1 个来源] ·

本文解释了自然语言处理中使用的神经网络的基本计算。它详细说明了单词如何首先被转换为数字令牌ID，然后由网络层进行处理。每一层都执行带有学习权重的矩阵乘法，然后进行ReLU等非线性激活函数，将输入向量转换为新的表示。文章强调了GPU如何加速这些可并行化的矩阵运算，并将其与循环神经网络（RNN）的顺序计算进行对比，解释了Transformer为何能更有效地扩展。 AI

    神经网络究竟计算什么：从Token ID到矩阵乘法

    <p>NLP models cannot process words directly, which is why tokenization[1] exists. Tokenization ends with a list of integers — token IDs like <code>[30642, 1634, 318, ...]</code>. That list is what actually gets fed into a model. This article answers why NLP models cannot process …
