LSTM

Also written: long short-term memory

An RNN with gates that decide what to keep, forget and output, so it can carry information across many more steps.

Other terms from the same lesson

• GRU: A simpler cousin of the LSTM with fewer gates. It also helps an RNN remember across long sequences.
• hidden state: An RNN's running memory: a list of numbers it updates after each word and passes on to the next step.
• RNN: A network that reads a sequence one step at a time, carrying a memory forward.
