The log-derivative trick is based on a simple rule from calculus: the derivative of with respect to is . When rearranged and combined with chain rule, we get: 3. Log-Probability of a Trajectory. The log-prob of a trajectory is just 4. Gradients of Environment Functions. The environment ...

We're not knocking calculus. We love calculus, and Sylvain has even taught it at the college level, but we don't think it's the best place to start when learning deep learning! In deep learning, it really helps if you have the motivation to fix your model to get it to do better....
