Differentiability in Generative Adversarial Networks
I've got some questions about the differentiability condition of GAN's, i.e. both G and D need to be differentiable wrt. their inputs and the parameters describing them. It's of more mathematical nature and I just couldn't find a clear answer to…

Poisson log-likelihood is concave but not Lipschitz-continuous?
According to He et al. (2016), the log-likelihood of Poisson models,
$$
L (\beta) = \sum_{i} - \log(x_{i}^{\mathsf{T}}\beta) + y_{i}x_{i}^{\mathsf{T}}\beta - \log y_{i}!
$$
for a random variable, $y_{i} \sim \text{Pois}(x_{i}^\mathsf{T}\beta) $, is…
