In the context of LSTMs, which gate decides what information from the previous cell state should be discarded?
Show answer
Forget gate
The forget gate outputs a number between 0 and 1 for each number in the cell state, where 1 represents 'completely keep this' and 0 represents 'completely get rid of this.' This mechanism helps the network manage long-term dependencies by clearing irrelevant information.
