Lstm activation sigmoid
Web21 okt. 2024 · The input gate is a sigmoid activated network which acts as a filter, identifying which components of the ‘new memory vector’ are worth retaining. This … WebLSTM is then concluded with the final, output gate. Its output is computed by first passing previous hidden state and the input to the sigmoid function and then multiplying this with the updated state that was passed to the tanh function. The output is the new hidden state which is passed to the next time step along with the new cell state.
