Webb25 okt. 2024 · Several variants of the Long Short-Term Memory (LSTM) architecture for recurrent neural networks have been proposed since its inception in 1995. Webb3 mars 2024 · However, this is not always the case, and there is a trade-off between the network capacity and generalization performance. A more extensive network may have more capacity to remember past data. Still, it may also be more prone to overfitting, which can affect the generalization performance of the network on unseen data.
