Hey folks. Over the past couple months we’ve been working on a fairly significant PR designed to overhaul Turing’s internal API to make future development a lot easier. Many of these changes are never something a use wi…

Hi! I’m working on some changes in Soss, and they’re different than the usual way of going about PPL. Thought I’d share them here in case other are curious or have any thoughts blah blah (the usual stuff on that front) …

For independent observations from some distribution, we end up doing a lot of sum(logpdf.(myDist, x)) But in some cases, the algebra simplified a lot, and we can just track sufficient statistics. A common example of th…

For probabilistic programming in particular, it’s critical to be able to use distribution-related functions (especially logpdf) in non-standard ways. For example, I would love to be able to call logpdf(TDist(nu),x) where…
