Iterative α-(de)blending and Stochastic Interpolants

As someone who's just watched from the sidelines, I found the article and papers really interesting. I found the iterative alpha blending/de-blending to be better explained in the paper though.

Took me back to my path tracing days, with things like importance sampling[1] and Metropolis-Hastings[2].
