WebJan 30, 2024 · These gates are essentially vectors containing values between 0 to 1 which will be multiplied with the input data and/or hidden state. A 0 value in the gate vectors indicates that the corresponding data in the input or hidden state is unimportant and will, therefore, return as a zero.
