LSTM (Long Short-Term Memory) is a type of RNN designed to remember long-term dependencies in sequential data.

• LSTM addresses the vanishing gradient problem found in standard RNNs, allowing it to learn long-term dependencies.

• An LSTM cell consists of three gates: input gate, forget gate, and output gate, which control the flow of information.

• Example: LSTMs are used in natural language processing tasks like language trans...read more
