I just discovered this field; I needed an algorithm to compute a low rank approximation of a large covariance matrix without first building the matrix. I'm using algorithm 16 in th…

Nice to know that numba has these features; I'll have to check it out at some point!

I haven't tried numba but I've heard good things about it! Nice linked tutorial. If I understand correctly, you pass in jitted functions (using numba, and jax) into iminuit which d…

I've been using JAX ( https://jax.readthedocs.io/en/latest/ ) for scientific computing in general (in particular MCMC algorithms), as it's really fast. Even on a CPU you get massiv…

I hadn't seen that; thanks!

There are probably a bunch of alternatives for this. For example a friend built Reading List which I've heard is good ( https://apps.apple.com/us/app/reading-list-book-log/id121713…

The way to represent negative numbers (page 3 of the manual) is really cool: to do "a - b" you add a to the complement of b (with the complement of b being 2 - |b|). It feels reall…

Perhaps an alternative to look into: Numpyro [1] has a JAX backend so can be really fast when compiled; and it can run on GPUs. So that might be helpful for your problem with loads…

I guess (good) podcasts are the modern equivalent!

The author used the "intelligent driver model" (IDM): https://traffic-simulation.de/info/info_IDM.html It's a system of ODEs that describes the dynamics of each driver. So the inpu…

Sounds cool! What's the company? I haven't heard of many companies needing CFD

I’m doing a postdoc in stats/ML and mainly writing MCMC algorithms. Background: phd in computational statistics. I’ve used a lot of Python and a bit of Julia. I’ve recently started…

this is great. The Kohl concert is hard to type at the right pace though :)

Cool! Yeah I tried a pdf and it generated a bunch of URLs ;)

This is really cool! How did you do the encoding though?
