LSTM networks overcome RNN memory limitations with gating mechanisms

The Long Short-Term Memory (LSTM) network was developed to address the limitations of traditional Recurrent Neural Networks (RNNs) in handling sequential data. Vanilla RNNs struggle with remembering information over long periods due to the vanishing gradient problem during training. LSTMs introduce a more complex internal structure with gates that allow them to selectively remember or forget information, thereby overcoming the limitations of RNNs and improving performance on tasks like language modeling and time series forecasting.
