Web20 aug. 2024 · Traditionally, LSTMs use the tanh activation function for the activation of the cell state and the sigmoid activation function for the node output. Given their careful design, ReLU were thought to not be appropriate for Recurrent Neural Networks (RNNs) such as the Long Short-Term Memory Network (LSTM) by default. Web19 sep. 2024 · Conclusion. Simple neural networks are not suitable for solving sequence problems since in sequence problems, in addition to current input, we need to keep track of the previous inputs as well. Neural Networks with some sort of memory are more suited to solving sequence problems. LSTM is one such network.
