What is Input Gate? Why does it exist? Where does it appear in LSTM?
Draw or describe a visual model of Input Gate. What does it look like conceptually?
Work through a concrete manual example of Input Gate with real numbers or pseudocode.
Implement Input Gate from scratch in Python. Keep it minimal — just enough to see it work.
How is Input Gate different from related concepts in LSTM? What are the trade-offs?
Explain Input Gate in plain language using an analogy. Could a non-expert follow it?
