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.

Car analogy?

[sinij]

Could someone please explain this with a car analogy?

[gstoddart]

Spinners, a big antenna, and fuzzy dice make for one bitchin' ride.

Beyond that, I got nothing.

It's a cannon.

I understood some of those words

It seems like the kind of thing a random science-word generator would produce.

This is news for nerds.
It's a pattern detection strategy that relies on generating waves with input data, interweaving them physically, and using arrays of antennas to detect patterns.
That's from the first couple of paragraphs.
I don't know a lot of physics, but I am a nerd, and I like this kind of thing, so I can learn about cool stuff.
If you don't care about it, you can look at other stories that talk about tesla and bill gates and whatever else. Posting is not mandatory.

I would come here more often if orasio wrote the summaries.

The problem with the summary is that it assumes the reader is already familiar with the device. Your summary does not suffer from that problem. For instance "prototype eight-terminal device consisting of a magnetic matrix with micro-antennas to excite and detect the spin waves." WHAT spin waves? What is a terminal in this context and why is the a key thing in the summary? The summary already presupposes too much, even for a technical news site.

On the flip side, it would be nice if you didn't also insult the person who asked for clarification. The summary is indeed confusing.

+1 for insightful explanation.
-1 for being an asshat about it.

I'm not sure his point was that he didn't care about it.

I also found the summary fairly opaque, although that is likely a reflection of my minimal understanding of math and physics. The editors usually provide summaries of complex topics that are a little more approachable for the layman but I suppose I could always flout the law and RTFA.

Re:Huh?

Don't worry, scientists are working on a device that can recognize them.

After reading that summary I feel like a juggalo. "...F*cking magnonics, how do they work?.."

Re:Huh?

[gstoddart]

Nope, stupid human can't type ... magnonic is apparently a real thing.

Re:Huh?

[SwingKing]

Looked at that page, which lead me to the SpinWaves page, which had the text: "The simplest way of understanding spin waves is to consider the Hamiltonian {H} for the Heisenberg ferromagnet:" at which point my head exploded and I went back to watching Star Trek reruns. At least there the technobabble make sense...

Back to the analog future

[jtara]

It's a pattern detection strategy that relies on generating waves with input data, interweaving them physically, and using arrays of antennas to detect patterns.

So, it's an analog computer.

If I could explain it in 30 seconds, it wouldn't be worth a Nobel Prize.

Simplicity is good, but not always attainable.

Ok I'll try:

[tomxor]

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.
