Q: Compute derivative of an expectation over a reparameterized distribution

Reedee AlexanderIf $p_\theta(x)$ can be reparameterized as $p(\epsilon)$, s.t. $x=g(\theta, \epsilon)$, why $\frac{\partial}{\partial \theta} \int f(x) p_{\theta}(x)dx = \int p(\epsilon) \frac{\partial}{\partial \theta} f(g(\theta, \epsilon)) \frac{\partial}{\partial \theta} g(\theta, \epsilon) d\epsilon$? It i...

A: Tag management 2022

James ArathoonProposal: Add the tag [tag:foundations-applied-math] The mathematician Norman WildBerger has been stressing on his YouTube channel (https://www.youtube.com/c/njwildberger) his non-belief in infinite sets and also the real numbers and their associated arithmetic operations. That is Real numbers r...
