New Device Could Greatly Improve Speech and Image Recognition 67
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.

You may remember the bit in The Hitchikers Guide about London based designers driving their Porsche against a tree with their leather jacket strapped at the front of the car to give it the perfect pattern of lines and that air of being-used-fullness.
TFA describes what is the analogy of doing this with 1000 Porsches on the same leather jacket and later read the license plates of each of them within 100 nanoseconds from the scratches in the jacket.

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.

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.

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.

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).

From what I could tell from the article, it appears to focus on both. The device allows them to quickly create and store a pattern. It then allows another pattern to be created and quickly compare the patterns.

From what I could tell, the advantage of the magnetic spin is that with an 8 terminal node, it can quickly create a matrix of 1,000 bits of data. It can then compare that matrix with a stored matrix. With several nodes working in parallel, it takes the same time to compare 1,000 bits of data as 10,000
