Visualizing transformers and attention | Talk for TNG Big Tech Day '24

This podcast features a Q&A session with Grant Sanderson, focusing on his work visually explaining transformer models in large language models (LLMs). Sanderson explains the inner workings of transformers, detailing the processes of tokenization, embedding, attention mechanisms (including multi-headed attention), and the role of multilayer perceptrons. He uses the example of how adjectives modify nouns to illustrate the attention mechanism, explaining how the model learns associations between words. The session concludes with questions from the audience covering topics such as training stability, the use of humor in presentations, and the potential of analog computing for LLMs. A key takeaway is the explanation of how the attention mechanism allows for parallelization, crucial for the efficiency of LLMs.
