Thank you for your interest in our work. The equality from Eq. (13) to Eq. (14) is obtained by multiplying the same quantity, $p_t(x_t|Y=y)$, in both the numerator and the denominator. A detailed line-by-line derivation is given below. Please feel free to contact me if you have any further questions.
