LSTM (Long Memory)
An LSTM is an RNN with gates that help it remember important things for longer.
What it does
An LSTM is an RNN with gates that help it remember important things for longer.
Gate: A valve for data flow • Cell State: Long-term storage
How it works
- Use a forget gate to drop unneeded information.
- Use an input gate to save useful new information.
- Carry important memory forward.
Uses & Applications
- A text app can remember the start of a long sentence.
- A weather system can remember older weather patterns.
- A phone keyboard can use earlier words to guess the next word.
In short
It is like a diary that keeps important events and forgets tiny details.
Try it yourself
Choose what a memory keeps and shows
Three gates act like taps. One keeps old memory, one adds a new clue, and one controls how much memory is shown.
Your turn
Change one setting at a time. Reset example puts everything back.
Control memory gates
