Attention Mechanism

Summary

A technique that lets a model weigh which parts of the input matter most for each output step — the single most important idea behind modern LLMs.

• 1Read the original 'Attention Is All You Need' paper's intuition section (skip the math at first).
• 2Implement a simple attention mechanism from scratch on a toy sequence task.
• 3Visualize attention weights on a real example to see what the model 'focuses on.'
