- Ans.
LSTM is a type of RNN with additional memory cells to better capture long-term dependencies.
RNN stands for Recurrent Neural Network, while LSTM stands for Long Short-Term Memory.
LSTM has additional memory cells (input, forget, output gates) to better capture long-term dependencies.
RNN suffers from vanishing/exploding gradient problem, while LSTM helps alleviate this issue.
LSTM is better suited for tasks requiring long-...
