Meanings in context

Article-grounded definition

the observation history.

a_t \sim \pi_\theta(a \mid o_{\le t},\ h_t,\ g),

This equation states a bound: one expression must stay on the indicated side of the other under the article’s assumptions.

o_{\le t}

the observation history.

a_t\sim\pi_\theta(a\mid o_{\le t},h_t,g), \qquad o_{t+1}=E(s_t,a_t),

This equation states a bound: one expression must stay on the indicated side of the other under the article’s assumptions.

a_t \sim \pi_\theta(a \mid o_{\le t}, h_t, g),
