Replace _{ by \_{ to disable Markdown transform.

s_t = f(U x_t + W s\_{t-1} )
Replace \ by \\ to disable Markdown transform.
Such as:
\\{ A\_{i,i} \\}
Prepend \ before &=.
Such as:
\begin{aligned}
E_t(y_t, \hat{h_y}) &= -y_t log{\hat{y_t}} \\cr
E(y, \hat{y}) &= \sum_t{E_t(y_t, \hat{h_y})} \\cr
\ &= -\sum_t{y_t log{h_y})}
\end{aligned}
