    Variant of an LSTM cell aimed at reducing computational dependency across time steps.
    Formally described as:

    (1) f[t] = sigmoid(W1[t] * x[t] + b[t])
    (2) c[t] = f[t] . c[t-1] + (1 - f[t]) . W2[t] * x[t]
    (3) h = ReLU(c[t])

    where:
        . represents elementwise multiplication;
        x[t] is the input at time step t;
        f[t] is the output of the forget gate at time step t;
        c[t] is the cell state at time step t;
        h is the output of the unit.
