Minimum Description Length is such a parsimonious and easy to understand description of entropy and randomness. Anything by Chaitin is well worth reading.
@DavidTanzer Would you please add a link to this report in the Azimuth library page on biodiversity. PS Didn't we used to have a direct messaging facility on this site?
@johnbaez cited the Dsgupta report in his brilliant 'Mathematics in the C21st' talk at the topos Institute in March this year https://www.youtube.com/watch?v=lUqqQXFTHUY. If the first part of the talk which is exclusively aimed at mathematicians was…
Dan Ghica at U. Brum ran a course for primary school children quite a few years ago. I tried to access it for a friend who is a senior lecturer in primary science at Brum City Uni. but although advertised then as open access it wasn't. Now some of i…
Daniel, if you haven't come across it you might enjoy Brillouin's 1956 originating text "Science and Information Theory": https://www.informationphilosopher.com/solutions/scientists/brillouin/
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…
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.

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. :)
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.
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.
@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…
