Transformer Architecture

Definition

A groundbreaking deep learning architecture introduced by Google in 2017 (in the paper 'Attention Is All You Need') that completely revolutionized NLP by processing sequential data in parallel rather than sequentially.

Explain Like I'm New

Before 2017, AI had to read a book word-by-word. By the end of the page, it forgot the beginning. The Transformer architecture allows the AI to look at the ENTIRE page simultaneously. This made AI vastly smarter and vastly faster to train.

Real World Example

The 'T' in ChatGPT stands for Transformer (Generative Pre-trained Transformer). Without the Transformer architecture, modern LLMs would literally not exist.

Common Use Cases

  • •LLMs
  • •Computer Vision (Vision Transformers)
  • •Audio processing

'Attention Is All You Need'.

Question

Why faster on GPUs?

Answer

Because they process data in parallel. Older models had to process word #1 before they could process word #2. Transformers process all 10,000 words in a document simultaneously, fully utilizing the massive parallel computing power of modern GPUs.
