I know someone who can sing to match a melody from memory very accurately. They sing on key. But they have a hard time singing to match a single pitch, and they have a very hard time naming whether two consecutive pitches are ascending or d

I just read a comment above that discussed this timbre sensitivity. In any octave the A sounds buzzy? What about on any piano? Do all 88 keys produce a kind of unique timbre signature for you?
753.
by gugagore 8y ago
I'm interested in this idea that a piano has a distinct timbre per note. Surely the most distinct thing between two notes is their pitch. But you're saying people pick up on the harmonic signature more readily? I can here the diff

The proliferation of apps for musicians on iOS (drums, guitar amps) is explained by the iOS's longstanding API for low-latency audio. I hope we can expect the same kinds of apps, with usable latency, for Android now too.

Two that I run into all the time: 1. pairwise iteration over a (cylic) list of points representing the ordered vertices of a polygon will give you a sequence of edges 2. np.diff, takes differences between consecutive pairs. Sometimes you ha

I ran into this when trying to process .srt (subtiles) files. The timestamp information is encoded in ASCII, and the actual subtitle text you would like to pass through unaltered. (In my case, I was just adjusting the timestamps).

I just tried to make a monotonous sound with my vocal chords while changing my mouth cavity to a melody, like in the "chhh" experiment, or as if I were whistling, and for me it's kind of impossible. If my vocal chords are vib

That's a bit too reductionist, right? Or perhaps you could elaborate? As it stands it sounds like "it's all just atoms" when someone asks "how does a neuron fire? Someone must have studied that."

>The costs in making sure things are tied out (ie, all amounts match to the penny) seem pretty high. Could you elaborate on why it seems high? What you're describing is computations on distributed systems, and I'd be surprised

I agree. I was just anticipating the common response to that challenge, or any other "static" perception challenge, which is "but there is a map"

But if snow occludes lane markings, which is what the parent was discussing, then no amount of sensing helps you see them, right? (You can have a map with lane markings and localize on that map, though)
762.
by gugagore 8y ago
That helps with localization only, right? Not with any other perceptual tasks?

I don't think you can simply assert that. People sometimes do try to avoid naming something twice, especially if it has an unwieldy name. For example, to cube a quantity, I don't like to write "x x x". Imagine if x had

For the first example, with the ternary operator, I think the original has an advantage that it does not mention `Armed` twice, unlike the improved version. The presenter mentions that there are a few extra characters, I know, but my issue

A Fourier transform of what? If you have a reference, I'd love to learn more.

I have looked into it, that's why I felt comfortable replying in the first place! ;) Can you explain why dual quaternions are more suited and for what? I can understand the appeal of having "one number" to represent a rotati

by gugagore 8y ago
It's not dual-quaternion anything, though. (Also you can implement it with matrix logarithms and exponents, no unit quaternions necessarily needed)

by gugagore 8y ago
You can just interpolate translation and orientation each individually (translation using linear interpolation, since it's an affine space, and orientation using SLERP or the matrix exponential and logarithm), and you should get the sa

Thanks for those details. I am glad to have seen the demonstration. I didn't know they removed it in 2016. I believe the better link is https://en.wikipedia.org/wiki/Divided_differences

It might have gone into the GHz range, but I'm guessing with a narrow bandwidth. It's the bandwidth that determines the sampling rate needed.

You might enjoy articles from BetterExplained. For example: https://betterexplained.com/articles/q-why-is-e-special-2-71... There might be an article about this specific technique.

I agree it's not a fair comparison. Your analogy, though, confuses latency and throughput.

It's useful to be able to give names to things and it's also useful to not be able to give names to things. It could and could also not be useful to give names to all the subexpressions in the following w = a(b(c(x,y),z)) You coul

Just because you don't, like, literally know what it means, doesn't mean it means nothing! In any case, I could care less.

I'm curious if you know any sign languages. I think you have to have some proficiency with the French sign language family (e.g. ASL) (beyond beginner because beginners are very brittle to changes in accent and style) to judge Koko&#x2

It's something in between the two possibilities you describe. Each human pixel in the image is labeled with an index and two coordinates: x, y (u and v are the traditional names, but think of 2D x, y coordinates) The index specifies wh
