Hi all,
I am looking for some guidance on how to approach a computational problem I have, hopefully using some of the amazing julia packages! This is early stages, and more conceptual at this point. I want to get some high level opinions on the best computational framework and associated packages.
In essence, I am performing inference on the end points of a random walk on a graph. In other words, suppose that I have some graph G = (V,E) and a stochastic process X(t) representing a random walk on the vertex set V.
I want to estimate P(X(T) = v | X(0) = v0) in the most efficient way possible. Computationally, I have a method of drawing samples, i.e. realised walks. This is a black box calculation - it is the output of a complicated julia function.
Any advice, pointers, recommendations for this probabilistic programming newbie? The graph has around 10,000 vertices, and so I feel like I need an efficient sampling algorithm in order to do anything meaningful. However I am unsure if this is possible given that samples come from a black box calculation.
Thanks in advance for taking the time!
