Lastly, i'd like to give a shout-out to dan marthaler, a helpful commenter on this blog, who pointed out that the pmf of the multivariate noncentral hypergeometric distribution would help evaluate the pmf of the gumbel sorting scheme.
For x ≥ 0 and c 0 in jkb the two shape parameters b a are reduced to the single.
Given the distribution parameters they can be used to investigate their statistical properties or to sample non-uniform random numbers. All the distributions implement a common set of operations such as evaluating the density (pdf) and the cumulative distribution (cdf) at a given point, or to compute the mean, standard deviation and other.

Both in the relaxedonehotcategorical distribution implementation and the original jang’s paper, the logits are clearly normalized. However from jang’s notebook implementation which is where pytorch got its gumbel softmax from, the input to that function is straight out from a linear layer, meaning it is not normalized.
Also, included is a jupyter notebook which shows how the gumbel-max trick for sampling discrete variables relates to concrete distributions.

Survival analysis studies the distribution of the time between when a subject comes under observation and when that subject experiences an event of interest. One of the fundamental challenges of survival analysis (which also makes it mathematically interesting) is that, in general, not every subject will experience the event of interest before we conduct our analysis.
