In this video, we discuss the evolution of the classic Neural Attention mechanism from early adoptions of Bahnadau Attention and more specifically Self-Attention and Causal Masked Attention introduced in the seminal "Attention is all you need" paper. This video discusses more advanced forms of the Multi Headed Attention such as Multi Query Attention and Grouped Query Attention. Along the way, we also talk about important innovations in the Transformers and Large Language Models (LLMs) architecture, such as KV Caching. The video contains visualizations and graphics to further explain these concepts.
