$r_\phi$

This entry links every published equation using this exact notation. Its meaning may change between equations.

Used in 5 equations

P(y_A \succ y_B \mid x) = \sigma\big(r_\phi(x,y_A) - r_\phi(x,y_B)\big),

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.

\max_\theta \; \mathbb{E}_{x,\, y\sim\pi_\theta}\big[r_\phi(x,y)\big] \;-\; \beta \, D_{\mathrm{KL}}\big(\pi_\theta \,\Vert\, \pi_{\mathrm{ref}}\big).
