Movie about a healthy algorithm for matching kidney transplants

This is a fun movie. Nice motion graphics, and camera work. The sound design is good too, although I found the jazz in the background distracting. And I love this research area. I think some colleagues at CMU were starting to work on it right when I was leaving grad school. I’ll share it on healthy algorithms went I have some time to post things.

Dear Abraham,

I hope this email finds you well. I am enjoying your blog!

I am writing to let you know about a short documentary that features me and my husband and a nice mathematical modeling problem for helping people get kidney transplants. Its moving principle is to sell operations research to a lay audience by explaining the kidney exchange problem in great detail. It has some nice animations that describe the steps of modeling and solving an integer program, at a level for absolute beginners.

Maybe you’d find it interesting enough to put on your blog. In any case, thanks for checking it out.

MCMC Convergence Diagnostics

I have revisited my approach to deciding if MCMC has run for long enough recently, and I’m collecting some of the relevant material here:

Last time I thought about it:

Blog about a cool visual approach:

Discussion on cross-validated:

Book with a chapter on this referenced there: (available as an eBook from UW Library, how convenient!)
