#probability-ratio

PPO's clipped objective for one sample is $L = \min\big(r A,\ \operatorname{clip}(r, 1 - \epsilon, 1 + \epsilon)\, A\big)$ with $r = \pi_\theta(a \mid s) / \pi_{\theta_{\text{old}}}(a \mid s)$. With $\epsilon = 0.2$ and an advantage $A = -0.5$, the ratio has grown to $r = 1.4$ during the update epochs. What is $L$?
