Why HN links it

HN commenters link Mark Reid's blog for a post on gun deaths versus gun ownership. One comment also notes he made Annotatr, a site for commenting on scientific papers, with boscoh.com.

Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?

  1. I also wrote a short blog post about this topic back in 2009: https://mark.reid.name/blog/warning-high-dimensions.html It great to see these interesting math facts continue to be discussed and presented in new ways.

  3. I wrote a very similar blog post a few years ago when I first encountered the same fact: http://mark.reid.name/iem/warning-high-dimensions.html Thanks to the comments, I learned this is a common warning, used in at least three textbooks.

  5. I see. I hope you would forgive me for assuming something so extreme. I would be curious to see some statistics on quantifying of police aggression (however quantified) versus civilian armament as covariates wrt total gun violence. One of the marginals of such a distribution are documented here: http://mark.reid.name/blog/gun-deaths-vs-gun-ownership.html but this doesn't say anything about the police side of the sto…

  7. I haven't used Hugo but my entire site is generated with Hakyll: http://mark.reid.name/ . I've found it works well for a mixture of blogging and more static content.

  9. Really nice presentation of divergences. I made a similar attempt (math + interactive JS visualizations) a long time ago for the Bregman divergences: https://mark.reid.name/blog/meet-the-bregman-divergences.htm... These visualizations are much nicer than mine though. Curious fact, the Bregman divergences are a different class of divergences to the f-divergences that intersect at the KL divergence. That is, KL is (es…

  11. I also did something similar when I switched my site to Jekyll. The usual blog content + header + sidebar format seemed unnecessary for me so I started by focusing on the content and building up from there: http://mark.reid.name/info/site.html I currently use justified alignment, but given the mounting evidence against it I might switch to ragged right next time I'm playing with the CSS.

  15. It makes me glad to see that Aleph (and ILP more generally) are still being used. It's a really powerful and interpretable way of constructing code from examples. I made a few contributions to Aleph as part of my PhD on doing transfer learning in ILP and really enjoyed working in Prolog. https://mark.reid.name/bits/pubs/unsw07.pdf

  17. This likelihood ratio approach highlights the fact that KL divergence is a member of the family of Csiszár F-divergences. These are measures of "distance" between distributions of the form E_Q[ F(p(x)/q(x)) ] where F is any convex function with F(1) = 0. This is kind of a generalization of log-likelihood where F kind of "weights" the badness of ratios different to 1. When F is -log you get KL divergence. Another cur…
