nice paper. i got stuck at point c but it is really interesting

[pat-alt]

Should have it ready by the end of the week/early next week. By the way, I know you're still mostly working on LA, but if you're interested in any of the other generator #103 let me know

[pasq-cat]

i guess i can try to understand the bayesian one for regression #392 but i do not make promises since the coding part seems much harder than what i did.

[pat-alt]

Yeh that's a bit of tough one but definitely super interesting! Alternatively, I think both #446 or #377 could be interesting (#377 probably the easiest one to implement)

[pasq-cat]

ok. i guess it's better if I try the easiest one first.
