Decoder

What is Decoder? Why does it exist? Where does it appear in Transformer?

Draw or describe a visual model of Decoder. What does it look like conceptually?

Work through a concrete manual example of Decoder with real numbers or pseudocode.

Implement Decoder from scratch in Python. Keep it minimal — just enough to see it work.

Try Decoder on a real example. Vary the inputs and observe what changes.

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

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

Build a small project or demo that uses Decoder as a core component.
