# 方法

(1)
\begin{align} bts = mt(s) = argmax_t \{ score(t|s) \} \end{align}

(2)
\begin{align} bts = mt(s) = argmax_t \{ P(t|s) \} \end{align}

(3)
\begin{align} P(t|s) = P(t_1|s_1) P(t_2|s_2)... P(t_n|s_n) = \prod_{i=1}^{n} P(t_i|s_i) \end{align}

(4)
\begin{align} bts = mt(s) = argmax_t { \prod_{i=1}^{n} P(t_i|s_i) } \end{align}

(5)
$$P(t|s)=P(s|t) P(t)$$

(6)
\begin{align} P(t) = P(t_1) P(t_2|t_1) ... P(t_{n-1}|t_n) = P(t_1) \prod_{i=2}^n P(t_{i-1}|t_i) \end{align}

(7)
\begin{align} P(t|s) = P(s|t) P(t) = \prod_{i=1}^{n} P(s_i|t_i)*P(t_1) \prod_{i=2}^{n} P(t_{i-1}|t_i) \end{align}
