I've heard the term "dithering" used for this, in electronics and a sort of related (reverse?) idea in displaying images on low color depth displays. I think. For example if you have a DAC generated 8-bit data, but you want f

This seems like it could be true for memories of facts, or something you can recite, like lyrics of a song. However for other kinds of memories, such as remembering a situation or a picture, I have heard (I'd appreciate a reference) th

I think it's less about intuitive understanding, and more about having a flat, numerical representation of a sentence that (qualitatively) satisfies some properties.

Is there anyway to display something in Linux without any color management? Can you access the buffer that gets read directly to the monitor? I've wanted to know whether two colors I'm displaying actually get distinguished by the

Just to be clear, NP hardness is a property of a problem class, not an algorithm. Similarly, "NP Hard" isn't the same as "worst case exponential time"

Why does it matter whether the solvers themselves have a common language if it's possible to make interfaces to solvers that expose a common language?

That's "course-grained reconfigurable architecture", for anyone else who didn't know.

You might be missing the joke in the OP. In any case the meaning of "full" in "I'm full" is colloquial and not absolutist. It's more like "I'm satisfied" and not "I'm stuffed" (whi

My guess is that the soundcard works pretty uniformly well between 100Hz and 15kHz. But the speakers and microphones might not.

Except you can't really get a signal in below 20Hz.

Let's see, LQR is an optimal control technique for linear systems given a model. Given a linear plant model and a PID controller, you can compute all the classic control metrics like phase and gain margins, settling time, and even how

by gugagore 9y ago
I think it's worth noting that cascaded PIDs are no more expressive than having a state-space controller. But probably it is easier to tune, as you say. Each integrator is one dimension of state.

I think you're saying that system is nonlinear because there's a t^2, but it's actually linear. The ODE for the system is certainly linear. You could choose a state space and describe the dynamics with linear operators. Solut

Spectral methods, or any methods where you have chosen a basis of continuous functions and are solving for weights produces solutions in the continuous domain. That's not a discrete model.

I hope most people care about understanding something more than they do distinguishing themselves in your view. For many people, concrete examples can help them understand an abstract idea. Even if someone doesn't grasp the full abstra

What are the different limiting values for a^b (a->0, b->0) considering all paths in the a-b plane? If there are as many points generated as are generated by considering only "Manhattan" paths, then I think it's appeali

I see! But scaling surely requires 2D interpolation, then, right?

I thought there was no 3D parameterization of SO3 that was singularity-free, except maybe axis*angle.

by gugagore 9y ago
It's just that you reduced it to "rotation matrices". And that's not what the trick is. The trick is factoring the rotation matrix into some easier matrices.
840.
by gugagore 9y ago
That's interesting. The sheer operations still require interpolation (just that, you don't need to do 2D interpolation, 1D works out), so you still need to interpolate. And the scaling also requires interpolation. So I'm not
