New Device Could Greatly Improve Speech and Image Recognition
jan_jes writes: Scientists have successfully demonstrated pattern recognition using a magnonic holographic memory device, a development that could greatly improve speech and image recognition hardware. The researchers built a prototype eight-terminal device consisting of a magnetic matrix with micro-antennas to excite and detect the spin waves. The micro-antennas allow the researchers to generate and recognize any input phase pattern, a big advantage over existing practices. It takes about 100 nanoseconds for recognition, which is the time required for spin waves to propagate and to create the interference pattern. The main challenge associated with magnonic holographic memory is the scaling of the operational wavelength, which requires the development of sub-micrometer scale elements for spin wave generation and detection.
Could someone please explain this with a car analogy?
It seems like the kind of thing a random science-word generator would produce.
Sorry, I got confused on the date.
Does the summary consist entirely of real words?
The Daddy casts sleep on the Baby. The Baby resists!
Resulting in improved leveraging of synergies and a minty fresh taste.
Honestly, I hope that makes sense to someone, because it sounds like computer generated gibberish to me. :-P
Lost at C:>. Found at C.
...for this year's "Science or Star Trek Technobabble?" championship!
... I don't see how this would be an improvement over replicating the same structure in silicon with a comparator per RAM bit with as many inputs as there are bits. Compare 8 bits or a thousand bits in a single compare operation for a "pattern" match and a giant AND gate for a single 1/0 match/no match result by supplying all the input data at once....
The only thing I can gather from the article is that this enables a massively parallel comparator. And then somehow that translates to someday faster pattern recognition for speech / image. Very scarce on details.
> magnetic matrix with micro-antennas to excite and detect the spin waves
Uh-huh.
You don't say.
Oh REALLY.
I got some excited spin waves, IF YOU KNOW WHAT I'M SAYING
The summary reads like it was written by the automatic computer science research paper generator.
This invention is all well and good, but how does it correct for sinusoidal deplenaration?
But can it do better than: "Dear Aunt, let's set so double the killer delete select all."?
Take it to the limit, everybody to the limit, come on, everybody fhqwhgads.
After reading that summary I feel like a juggalo. "...F*cking magnonics, how do they work?.."

Most of the time I gripe about press releases that massively overpromise, and don't contain enough real information to figure out what was actually done.
In this case they at least put the word "could" rather than "will" in the headline. And while the barrage of jargon that followed is incomprehensible to me, it's at least pretty clear that it's real work rather than science-by-press-release.
Now I'd appreciate it if somebody would come along and dumb it down to my level, which is still considerably higher than the fourth-grade education they usually target. So, in all seriousness: thanks to the PR team.
Article is less confusing than summary:
"The researchers built a prototype eight-terminal device consisting of a magnetic matrix with micro-antennas to excite and detect the spin waves. Experimental data they collected for several magnonic matrixes show unique output signatures correspond to specific phase patterns. The microantennas allow the researchers to generate and recognize any input phase pattern, a big advantage over existing practices. ... ...
The most appealing property of this approach is that all of the input ports operate in parallel. It takes the same amount of time to recognize patterns (numbers) from 0 to 999, and from 0 to 10,000,000. Potentially, magnonic holographic devices can be fundamentally more efficient than conventional digital circuits.
The main challenge associated with magnonic holographic memory is the scaling of the operational wavelength, which requires the development of sub-micrometer scale elements for spin wave generation and detection."
If I understand correctly it's something similar to MIMO only on much smaller scale.
So, it's an analog computer.
and don't ask questions about how it works
I tried this out in the lab but it melted my interocitor.
Long story short: It is a vibrator! At least that is what I could glean from the post :-P
OK, it sounds like really cool stuff...just, the terms used for it are out of my vocabulary at this point. Give it a few years and this will be regular words. Just like "RAM" was not a commonly used term 70 years ago...and it is now.
I am just going to straight call BS here. Go RTFA and look at the "figures". This is some straight made-up stuff. I wonder if there is a purpose, such as exposing the garbage you can get published in accepted scientific venues. The article is complete Quatsch.
I need an XKCD to explain this to me. Perhaps an entry for Randall's new book, "Thing Explainer"?
Aren't "spin waves" what Foxnews generates?
From what i can quickly gather from the article:
This is all based on magnonics, which in short - is the use of magnetic spin for binary storage and or logic. This device focuses on the later...
It does this by constructing a matrix of magnetic nodes that are effectively interconnected to neighbours (moor?) via spatial magnetic-spin sensitivity, these interconnects form the dynamic logic processing ability of the matrix.
I think that this is somewhat like a (soft) convolutional artificial neural network for image recognition, these are constructed out of a 2d or 3d matrix of nodes with weighted interconnects in a moor-neighbourhood arrangement. The difference here i guess is that a) it's done with magnetic spin (i really have no idea why this is an advantage, maybe i'm all wrong about this) and b) being an application specific piece of hardware each node works in parallel (this is trumped as the primary reason for the speed potential in the article).
... Big disclaimer: I am massively speculating because the use case is not made super clear.
Magnonic holographic memory sounds like the ideal storage peripheral for D-Wave Two quantum computers.
Who gets to write the device driver for it?
I hope it can rival: https://www.youtube.com/watch?...
From the summary, it looks promising.
(Sorry, somebody had to ask.)
