Because it is low frequency, it may suffer some absorption and other changes while it propagates through the ionosphere. So radiation propagation through a partially ionized plasma is a very important subject to understand the early stages of the universe. And there may be damping of the radiation due to collisions between electrons and ions, and electrons and neutrons, and other possible sources of damping.
So when this guy comes up with a new thing to do, how likely is it to propagate throughout the social network? So the rate of propagation of strategies through the medium, the social network.
That's actually not the problem-solving algorithm at work. What's the propagation mechanism, well there are various ones.
That's actually not the problem-solving algorithm at work. You've got a propagation mechanism.
Commentator: Oh good! Belva Davis: Commentator: We are glad to contribute to -- Belva Davis: Right. Commentator: the propagation of the use for your mantra. That's great. Belva Davis: Yeah. Commentator: Here at Google, we call ourselves Googlers here. I don't know if they, they taught you that term in your lunch or in your tour. And a lot of us work in different functions.
And the next morning, the leaves were falling off. So if you have crack propagation , it hits a crystal and can't go any further.
Why the sets had different spacings and what the different angles were. And he turned that eventually into very successful surf forecasting business. Because if you talk to Sean he's still today completely obsessed with understanding the propagation of waves across the ocean. This is a chart he drew early on where he was trying to -- it was just a hand drawn chart that looked at the chart guide where he was actually looking at the bathymetry
So it turns out to be surprisingly connected to a lot of problems in partial differential equations, in number theory, in geometry, combinatorics. For example, in wave propagation , you splash some water around, you create water waves and they travel in various directions. But waves exhibit both particle and wave-type behavior.
Redshifted-- so it will become, actually, an even longer wavelength. And so there are issues of the atmospheric propagation of this radiation through the atmospheric. Because it is low frequency, it may suffer some absorption and other changes while it propagates through the ionosphere.
In India, only a couple of places-- at least, I know only one place where this work is going on, but it needs to be done, I think, So waning density-- it will decide where the shortwave ionospheric wave propagation will take
It's like what nature did is just discover these neural processes that allow us to build models of the world and then just repackage them And there's no sort of rigid back propagation phase that's going on globally throughout the network.
But it has a variant, which gives differential privacy. So for example, back propagation in neural networks or stochastic gradient descent have differentially private variance. So differential privacy has kind of just in recent years started to make it out of the lab or maybe kind of more precisely off the whiteboard
Well, you can write down the equations here. And what you can do is you can look at the propagation of new strategies across this population. So when this guy comes up with a new thing to do, how likely is it to propagate throughout the social network?
there were no charges of violence, that the charges in Arabic were-- They're quite comical, actually. which means, "Propagation by speech and writing for the ideas of a banned organization." We were charged for ideas.
In India, only a couple of places-- at least, I know only one place where this work is going on, but it needs to be done, I think, For example, for ionospheric wave propagation , it is the deciding factor from where the waves would be, radio waves would
And they could just barely do it with natural, with the natural things that are in the environment. and bit-rate speed, and speed of propagation .
Lewis Lapham: Richard Gingras: I mean to that last point while someone, while we, while we hunt for a questioner, if not I'll jump in with one. But it's interesting that whenever there's a new medium that allows the propagation of more information, the first concern is that that's just gonna yield more junk. And of course that's true, but it also seems true that the wheat to chaff ratios over time stay about the same.
- You look at the net effect of it, and it's actually been pretty negative by a lot of measures. People have suffered. - It's not only dangerous in terms of disease propagation , but anything malevolent now has conduits that it didn't used to have. - If we were all connected to everyone else on the planet completely at random, then it would be almost a mathematical certainty
And the next morning, the leaves were falling off. - One study notes that, "Experiment has shown that no detectable crack propagation occurs in rubber undergoing crystallization until the stress is so high
It's like what nature did is just discover these neural processes that allow us to build models of the world and then just repackage them This is a very different learning paradigm from the typical kind of supervised learning paradigm that we used with back propagation today.
I mean, yeah, the science was both the protagonist and the antagonist in that film, wasn't it? Sure. The antagonist was the Kessler syndrome and the propagation of orbital debris. And the solution, there were several scientific solutions that just sequentially solved one problem at a time, till you get to the end.
And then they analyze the data. And they get trained in lots of science data analysis, error propagation , statistical techniques. Most don't go on to become professors of astrophysics at universities.
So this is the result of social media campaign that is helped along by improvements in the technology of propagation , in this case printing.
And finding out how that happens, how they used what's called "stigmergic propagation " to change their environment and basically record onto the real world by laying down
Gatherings that are that are put together entirely by um last minute sort of email or text message propagation which
It's like what nature did is just discover these neural processes that allow us to build models of the world and then just repackage them systems. We're hopeful that we can get to a purely local unsupervised learning system as well that's as good as systems that are trained via end-to-end back propagation .
It's like what nature did is just discover these neural processes that allow us to build models of the world and then just repackage them You know, I was at grad school in the '80s as well, late '80s when back propagation was just coming out.
And that will tell us that it's not something that's happening with the neutron star, it's not something that's happening as a propagation
So the key thing is, as that gravitational wave propagates, it transfers to the direction of propagation .
And so they had this very simple, but very clever idea for how to do it, which is you run foreign propagation of the network up to some middle layer
