Both good questions. It could very well be that low dimensionality is simply a byproduct of the fact that neuroscientists train animals on such simple (i.e., low-dimensional) tasks. This paper argues that [0]. As for your first point, it is

Agreed, it's really cool :). A lot of this is very new -- it's only been in the past decade and a half or so that we've been able to record from large populations of neurons (on the order of hundreds and up, see [0]). But the

If I’m recording from N neurons, I’m recording from an N-dimensional system. Each neuron’s firing rate is an axis in this space. If each neuron is maximally uncorrelated from all other neurons, the system will be maximally high dimensional.

Sure, but the neural activity is actually low-dimensional (see Extended Fig 5e). By day 4, the first two principal components of the neural activity explains 75% of the variance in response. ~3-4 dimensions is not particularly high dimensio

Your comment illustrates another way in which these institutions maintain exclusivity -- they hire and admit people that are already in them. I did my undergraduate in a run-of-the-mill liberal arts college. I managed to get into a post-bac

This might be a pretty naive question, but: in a hypothetical world where the vast majority of systems programming is done in "memory safe" langs, what would most vulnerabilities look like? How much safer would networked systems b

I struggle to think of a piece of software I've been as happy with paying for as ST. It's just a reliable and snappy text editor that _feels good to use_. Sure, it doesn't have all the fancy new things Atom and VSCode often d

In my day job I'm constantly reading PDFs. Being able to zoom in/out, scroll, and move the cursor with such low effort can even bring me a little bit of joy. It's not really about what is most efficient. Computing should feel

Our technology is finally getting into the realm of things where something like this might be made possible, for small brains such as those of fruit flies or zebrafish. Already we can perform near-whole-brain recordings of these animals usi

Anyone have a good resource on understanding the policies that govern the ownership and handling of data collected by an Apple Watch? I quite like that they can be used for tracking sleep, heart rate, and many other health-related items. Id

Wow, I just tried it out. This is really great. And it solves my interactive plot saving requirement. Easy as doing `Plotly.savehtml(fig, "test_fig.html")` :). Thanks!

I have, though I've mostly stuck with the plain PyPlot.jl package due to the familiar syntax and interactivity. Perhaps things have changed, but I just recall being frustrated at the inability to zoom in/out, and again save intera

I'm a graduate student that's switched almost completely over to Julia. Prior to it I worked in both MATLAB (the IDE is so nice, and writing out matrix computations is just great) and Python (for ML). Julia is absolutely nicer to

Are these things so important that we should give up the easier maintainability (and potentially, security) that comes from centralization and the standardization of user clients? I absolutely think projects like Matrix are worthwhile, but

I never use the DDG results when looking for something. People on here will sometimes say that the results are as good as Google, but it's just not true in my experience. I would switch completely to Startpage, but I value the !bang fe

The game is great on PC, and sure there are some bugs, but nothing catastrophic. I've been playing the game on GeForce Now and I was pretty amazed with how much game streaming tech has progressed since it was first introduced. There&#x

It might rather be due to the brain simply requiring a baseline level of excitability to be present in order for it to properly function. Many unconscious states are characterized by reduced activity throughout the brain. The thalamus, bein

There is work in anesthetized monkeys (the neural and behavioral signatures of anesthesia are similar to those of coma) demonstrating that high frequency thalamic stimulation is sufficient to restore some markers of wakefulness, even while

One way in which I've found the two to be incredibly similar: they're both very good at throwing me into the flow zone. And I love being there, which is why my full time job is basically programming all day long. They're diff

Completely agree. I've become increasingly convinced that we'll need a fundamental restructuring of the academy if we want to fix any of these issues. The fact that places like MIT or Stanford will hire professors simply because t

It's funny how industries whose entire basis lies in the racialized colonization of the global south become reconstituted in a way that maintains their existence, but further obscures their origin. Perhaps true justice would mean the c

Right, this is why the US GDP has grown by a factor of 20 in the past half century while adjusted average hourly wages haven't budged. What a frightfully naive point of view.

No. But those that lack the capital to be able to take appropriate countermeasures (largely in the global south) certainly will.
