If your data has a target that resides in a single vector, the number of output nodes in your neural network will be 1 and the activation function used on the final layer should be sigmoid. On the other hand, if your target is a matrix of One-Hot-Encoded vectors, your output layer should have 2 nodes and the activation function ... WebApr 10, 2024 · The output gate determines which part of the unit state to output through the sigmoid neural network layer. Then, the value of the new cell state \(c_{t}\) is changed to between − 1 and 1 by the activation function \(\tanh\) and then multiplied by the output of the sigmoid neural network layer to obtain an output (Wang et al. 2024a):
