  • Just one data point but this paper reports better correlation coefficient and lower RMS error for transfer learning cf. original data and superiority to PCA or kriging and "restores a missing spatial pattern of the documented El Niño from July 1877…
  • Jules Hedges' website is probably the goto site for stuff about open games: https://julesh.com/
  • A review in the BMJ of SARS-CoV-2 diagnostic and outcome prognosis preprints and peer-reviewed studies in a collaboration between european researchers and the Cochrane Prognosis Group finds them all subject to mostly sampling bias and clinically unu…
  • That list is v. useful. I've been happy to realise that it's a sort of curriculum for the project I find I've been trying to follow over the past few years. Even better is that rather than a single journal article reporting negative results it gives…

  • I find it reassuring that a sample of 2 sims: https://aspofrance.files.wordpress.com/2020/03/hlcovid19-16mars.pdf and Alison_L_Hill's https://t.co/GV5ErDkfE9 both show peaks not later than 100 days.
  • Here's Neil Ferguson et. al., Impact of non-pharmaceutical interventions (NPIs) to reduce COVID19 mortality and healthcare demand (2020). This has a description and the params, of the Imperial college task-force model which has changed the UK gov's …
  • I'd like to see the algorithm for the "nifty array-syntax trick that allows you to calculate a convolution between two ranges very compactly." Tnx for the offer. :)
  • Here's the Zang et. al. paper: Prediction of New Coronavirus Infection Based on a Modified SEIR Model (2020)
  • ICYM these, @JacobBiamonte started a draft blog article on creation-annihilation operators in the SIR model and @NathanUrban commented on discrete event simulations which links to EpSimS epidemology simulation software.
  • Nerilie J. et al., Coupling of Indo-Pacific climate variability over the last millennium (2020)
  • John wrote up the SIR model in the Azimuth library and his blog on network theory. This has Recovered and Resistant in the Petri net but it would be interesting to add the SEIR model to the page which adds Exposure to the SIR model as in a Covid-19…

  • @JanGalkowski @PaulPukite Plans of action wrt. environmental issues are an original part of the Azimuth blog and library. Due to difficulties in search/navigation you might not have come across either the wiki library article on Pascala and Sokolow…
  • @PaulPukite/@WebHubTel @JohnBaez's post on Green Mathematics doesn't refer the term to just organic networks. It does focus on networks but these include passive linear circuits and chemical reaction networks. Metron and John B. are working on air-s…
  • Re #51. The Azimuth Code project isn't inactive. Iirc I've just fixed access for @MatthewDoty, @ChrisGoddard and @PaulPukite. I still want to post code there.
  • Brent Yorgey's Typeclassopedia provides a useful conceptual hierarchy of Haskell types. https://wiki.haskell.org/Typeclassopedia
  • @DavidTanzer Thanks for your stalwart efforts developing and maintaining the website over the years. And also your very helpful exercise comments and tutorial materials. Just my 2c worth but what do you think is wrong with the current Azimuth home p…
  • There are plenty of plutocrat, neoliberal, "libertarian" shopkeepers who claim to be entrepreneurial geniuses. The little tinpot P. "Paypal" Thiel is another example.

  • @MatthewDoty Sorry I only just read your comment. I think I added you to the Azimuth github organisation as an owner so you can create any repos you like. If not just ping me here. FI. I don't think github supports nested repos so the whole site has…
  • @jangalkowski Nope, your hurricane analysis code didn't make it to github but I'm interested in these sorts of techniques as I did some work in the 90s on the UK's flood defence system and the civ. eng. consultant I worked with then has recently bee…
  • @JanGalkowski "90% full" is what I got when I clicked on your link posted in comment #9. I'm interested in any environmentally relevant code you've written. You're right about free github being only for code but @johnbaez and iirc @allanerskine ran …
  • @davidtanzer that azimuth-project/azimuthproject repo is just an obsolete initial port of code from some old azimuth-related repo which I disaggregated but never deleted.
  • @JanGalkowski "If Haskell is a niche language, then OCaml is a super-niche language" is one take on the comparison. Plus, original HoTT codes (much being written by @JohnBaez's long-term pal Mike Shulman) were written in Coq which is written in OCa…
  • @JanGalkowski there are plenty of new folks who've joined the Azimuth project from the MIT Haskell coding course. Some of them might write correct by construction, if only pedagogically environmentally useful Haskell/Idris code. All of Haskell is ho…
  • @WebHubTel Yep, like 10/12 members you're an "owner" with all permissions. I didn't know that there's a github sec. alert system. You must be signed up to it but I'm not. I found the report with that GHSA id in the github security db http://bit.ly/3…
