What is Top-K Retrieval? Why does it exist? Where does it appear in Vector Database?
Draw or describe a visual model of Top-K Retrieval. What does it look like conceptually?
Implement Top-K Retrieval from scratch in Python. Keep it minimal — just enough to see it work.
Try Top-K Retrieval on a real example. Vary the inputs and observe what changes.
How is Top-K Retrieval different from related concepts in Vector Database? What are the trade-offs?
Explain Top-K Retrieval in plain language using an analogy. Could a non-expert follow it?
