Neural Networks: How Token IDs Become Matrix Multiplications

This article explains the fundamental computations within neural networks used in natural language processing. It details how words are first converted into numerical token IDs, which are then processed by layers of the network. Each layer performs matrix multiplication with learned weights, followed by a non-linear activation function like ReLU, to transform the input vector into a new representation. The article highlights how GPUs accelerate these parallelizable matrix operations, contrasting them with the sequential computations of Recurrent Neural Networks (RNNs) and explaining why transformers could scale more effectively.

    What a Neural Network Actually Computes: From Token IDs to Matrix Multiplication

    <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 …
