Cross-Attention

What is Cross-Attention? Why does it exist? Where does it appear in Transformer?

Draw or describe a visual model of Cross-Attention. What does it look like conceptually?

Work through a concrete manual example of Cross-Attention with real numbers or pseudocode.

Implement Cross-Attention from scratch in Python. Keep it minimal — just enough to see it work.

Try Cross-Attention on a real example. Vary the inputs and observe what changes.

How is Cross-Attention different from related concepts in Transformer? What are the trade-offs?

Explain Cross-Attention in plain language using an analogy. Could a non-expert follow it?

Build a small project or demo that uses Cross-Attention as a core component.
