A paper of ours just got rejected from a leading computer science journal for being ‘too technical’ and for some disturbing reason the inner economist in me is really proud.

I'm not in the UK on this day, but if I were, I'd be going to this.

Can't wait to read it!

Big shoutout to Patrick Prag @ppraeg.bsky.social !!

Yes I am an editor too, you may thank me, even if you believe my rejection of your paper was dumb and unfair.

So, I said it. Back to reading the next shitty paper.

p.s. thanks again for asking; your tag made me finally get round to fixing about ten issues we had open on GitHub and internally over the weekend.

Always looking for some additional #dev #devops #datascience #genomic #frontend help on this, in case anyone is interested in collaborating on v2.0.0!

Charlie Rahal @crahal.com · Sep 1

Thanks for asking! Its almost like we made a way to automatically track this on a daily basis, @pietrobiroli.bsky.social 🤩!

This summer wasn't too bad to be fair!

Charlie Rahal @crahal.com · Sep 1

The first is with the Oxford EPSRC CDT in Healthcare Data Science 🧑‍💻💊, and the second with the DPhil in Population Health 🌍📊. Both need serious programming chops 💪, but each tackles different big questions — so hopefully there’s something here for everyone to get excited about! 🚀

Charlie Rahal @crahal.com · Sep 1

🥳 Thrilled to bits about this! The first project is with the forever brilliant @melindacmills.bsky.social, and the second with the dream team of @sanderwagner.bsky.social & @dvaldenegro.bsky.social!

I honestly can’t wait to begin supervising these exciting projects together🙇🙇🙇

💡🤖🔥 @keyonv.bsky.social's talk at metrics-and-models.github.io was brilliant, posing epistemic questions about what Artificial Intelligence "understands".

Next (two weeks): Alexander Vezhnevets talks about a new multi-actor generative agent based model. As usual, *all welcome* #datascience #css💡🤖🔥

Charlie Rahal @crahal.com · Aug 27

Excited to contribute to this; very exciting stuff by @hggaddy.bsky.social, as usual!

i don't know you, but my thought is that i absolutely and entirely agree with you.

💡🤖🔥The talk by Juan Carlos Perdomo at metrics-and-models.github.io was so thought provoking that the convenors stayed to discuss it in the room afterwards for quite some time!

Next, we have @keyonv.bsky.social asking: "What are AI's World Models?". Exciting times over here, all welcome!💡🤖🔥

Charlie Rahal @crahal.com · Aug 4

Absolutely delighted to confirm forthcoming talks as part of the series by @bstewart.bsky.social and @andganna.bsky.social! Can't wait!

Charlie Rahal @crahal.com · Aug 4

💡🤖🔥The talk by @klint.bsky.social at metrics-and-models.github.io was truly brilliant. Important work; a clean/intuitive computational design & empirical application from the @itemrespwarehouse.bsky.social!

*Next:* Juan Carlos Perdomo on "The relative value of prediction" (v. excited about this)💡🤖🔥

Charlie Rahal @crahal.com · Jul 17

@ramina-sotoudeh.bsky.social gave an AMAZING talk yesterday as part of the #metrics-and-models seminar series👏. Next (30.07), we have @klint.bsky.social on "Reproducing Expert Judgement with Shortened Surveys using Simulated Annealing"🔥! See website for more; metrics-and-models.github.io!

Charlie Rahal @crahal.com · Jul 2

The first #metrics-and-models talk was fantastic🤗!

Next: @ramina-sotoudeh.bsky.social on "Antenatal Selection: A novel approach for assessing the genetic and ecological drivers of who survives to birth".

Hurrying to post about RobustiPy, i forgot this fun animation i made for teaching purposes (with @deevybee.bsky.social on the SABS R3 CDT) around when we started developing. Specification uncertainty is just _one_ type of uncertainty, though; our forthcoming work looks at the role of random numbers!
