(author here) default values are the best guesses for the parameters of the novel coronavirus based on my reading of the literature

(author here) - that is correct, those aren't sliders, just waypoints

good questions! (author here) I've had a hard time trying to find hard figures on these numbers, and am trying to steer as much from speculation as possible. Your second observatio…

See the literature on exact penalty methods. I believe the short of it is yes, for a large class of problems this works, but the new problem will not be necessarily easier to solve…

I guess the author is not claiming a well rounded (low bias) introduction to ML to statistics, but a highly biased and specialized (low variance) course that is tailored to the aut…

the illustration shows 4 an approximation with quadratic curves. There's no point drawing the one with 8 as it would be indistinguishable, as the article points out

I don't think so. This effect, at least as described, can change even as the phone remains static, e.g. if you head moves while the phone sits still on the table.

could you clarify what you mean by an open-loop system, and why it must be compared with a closed-loop one?

A simple example of this that has been shown rigorously is compressed sensing. Finding the sparsest vector, subject to linear constraints Ax = b is NP hard for general matrices, bu…

is this a real concern? it should be relatively easy to distinguish life on earth from life on mars, should it exist. Especially considering it comes from a completely new path of …

they did experiments on the 2016 Max-SAT challenge, which seems to me like a legitimate class of problem instances.

i enjoyed the presentation, he has a flair for the dramatic.

could you elaborate on this point? what you're saying sounds like dynamic programming, which does not reduce the state space at all, just saves on redundant computations (and is a …

When working over ssh, its handy to have a text editor for making small edits here and there. I'm very excited about this editor!

6 word answer PCA is the SVD of A'A

to those who are looking for a WYSIWYG editor which supports latex, try LyX. It's good and intuitive enough that I have used it as a tool for thought, and prefer to work straight f…

A fascinating aspect of this entire kerfuffle is that the meta story, the one about sensationalism and "bad journalism" is too, a form of media sensationalism that plays to the ear…

A great collection, but I thought the final diagram of http://www.datavis.ca/gallery/say-something.php that illustrated the orders of magnitude of radiation dosage was a great use …

It'd be interesting in hearing about how far along autonomy is with the model 3, it seems Tesla may be playing it down in this presentation?

Its very tempting to believe that because most of math/science (e.g.) is incremental, that all math is incremental. Once in a long while I stumble onto something really new, a theo…

i think this is the right approach, you're not after all, the person you were 5 years ago, or even a week. most interests change with time, I lose interest in a topic very fast, an…

i agree completely, and that what's happening is nothing more than brute force search. Though I do think this is still interesting as the reward here is potentially much more well-…

I think an analogy can be made with Bayesian statistics. In principle, Bayesian statistics requires no training, just a way of sampling from the posterior, usually done with expens…
