Here is a bit more realistic model of the riffle shuffle. These results show that you need between 3 to 8 riffle shuffles, depending on your skill. Notably, the number of needed sh…

This is something a bit different, the effect in the paper comes from the eigenvectors of the data matrix. I'm no expert on kernel density estimation, but since it is basically jus…

Sorry, I didn't have funding to pay the open access fees. The published version is very similar to the preprint: https://www.biorxiv.org/content/10.1101/2023.06.20.545619v1 Alterna…

Oh wow, didn't expect to see my paper here. Happy to answer any questions!

Looks like these are just phantom oscillations, a statistical artifact of doing SVD/PCA on smooth data: https://www.biorxiv.org/content/10.1101/2023.06.20.545619v1 You get the same…

Colemak and Rulemak work nicely together.

I would be curious to hear more about your dad's opera.

Is this the mattl I think it is? If so, hi!

Do people contact you?

Maybe a nitpick, but Aaron Swartz was probably quoting Richard Hamming: And I started asking, "What are the important problems of your field?" And after a week or so, "What importa…

I knew it had to be him when you said Sutton and Barto. Yeah, I think we just missed each other since your name sounds familiar.

Sounds like the classic 4th Floor SHM committee

I did my PhD on this topic. One classic result from biophysics is that, if all of your decisions have a fixed level of difficulty, then what the author suggests is (mathematically)…

It is definitely not true. One of the many trivial examples is that Betz cells only appear in motor cortex.

The name "Darktable" is a play on Adobe Lightroom, since "lightroom" is a combination of "light table" and "darkroom", both concepts from film photography.

36 hours too late for me - I deleted my 14+ year old GSuite account yesterday morning. Oh well, Fastmail seems great so far.

That is not what the term "autocorrelation" means. Autocorrelation is the correlation of a vector/function with a shifted copy of itself.

FYI, similar technology is already mature and commercially available, e.g., through Inscopix (no affiliation): https://www.inscopix.com/nvista Looks like the innovation here is get…

Once I needed a single LAPACK function (tridiagonal matrix multiplication) in a C Python extension. I spent an eternity trying to link to LAPACK reliably across platforms until giv…

Or you can just do this: https://github.com/bhargavchippada/forceatlas2/commit/7438e2...

Oh wow, this is a great idea. How do you deal with the lossy compression? There must be a lossless codec which uses the redundancy better than deflate?

Disclaimer: georgewfraser is my academic cousin. Neuroscience research is huge and moving fast. Researchers have trouble keeping up with the bleeding edge in their sub-sub-field, l…

"Surprise", or rather "specific surprise", is actually a technical term in information theory, e.g., see: https://iopscience.iop.org/article/10.1088/0954-898X/10/4/30... This doesn…

> One of the major reasons I hold the medical and bio community is such low esteem - they don't know what they don't know yet act as if they do. On one hand, this is due to poor sc…

There are ways we can measure perseveration in the lab, and so yes, it can be higher or lower in different people. If you want to look into it more, a popular way to measure it is …
