Encoder

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

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

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

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

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

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

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

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