> Microsoft senior optical scientist James Clegg loads a piece of glass into a system that uses optics and artificial intelligence to retrieve and read data stored on glass.
How are they using "artificial intelligence" for this?
- tantalor 7y ago"machine learning algorithms decode the patterns created when polarized light shines through the glass" Unclear why ML is required versus old-school methods.
- black6 7y agoThat was my thought. If the data is written in some specific format, shouldn’t it be able to be read just as easily, without resorting to ML?
- ben_w 7y agoI think the idea is to make it readable even if civilisation ends and we don’t have any record of the format when the tech is re-invented afterward — A built-in Rosetta Stone.
- EpicEng 7y agoBut you'd still need to be able to run the classifier, right? What's the difference between that and a piece of code that just knows the format? There's still a format here, regardless of how it's being decoded.
- ben_w 7y agoI’m not sure I follow. The idea (if it works is another matter) is that a future civilisation can say “we don’t know what this format is, let’s throw machine learning at it” and even though that machine learning system doesn’t know anything about the format when it starts, it can work it out on its own.
- EpicEng 7y agoThat would work regardless of the format, so why use ML today? Today you just write a decoder that assumes the format, in the future it can be reversed engineered using whatever means they have available to them.
- dobleboble 7y ago"As fans of The Mote in God's Eye already know, one remaining question must be answered for any data storage method expected to last for millennia—what happens when the technological and cultural context surrounding a storage medium collapses? Silica addresses this problem also, by using initial "ground truth" tracks. The team is using machine learning algorithms to re-read Silica's data, and in the event of the loss of those trained algorithms, fresh algorithms can train very rapidly on the "ground truth" tracks, which teach them how to interpret the rest of the data." https://arstechnica.com/gadgets/2019/11/microsofts-project-silica-offers-robust-thousand-year-storage/ https://arstechnica.com/gadgets/2019/11/microsofts-project-s...
- dflock 7y agoYou just need to get your civilisation back the point where you can write ML algorithms first.
- red75prime 7y agoAre our brains so inferior? Wouldn't someone who studies those ground-truth records long enough learn to see the data?
- dflock 7y agoYes, they would - and it actually says that in the article. But you'd then need some non-ml way to read & play it back, which would still require readily available computers & lasers, etc...
- moralestapia 7y agoML is the new way to refer to old-school methods such as regression, statistical inference, etc.
- exikyut 7y agoOhh, ML is the new term for AI now. We've finally accepted the computer doesn't have any information in it yet, and that we have to (somehow) feed some in. Heh.
- tomatotomato37 7y agoI'm pretty sure in this instance its pop sci speak for "somewhat better than usual statistical error correction system"
- kevin_thibedeau 7y agoFuzzy logic 2.0. ECC is just so last century.
- logfromblammo 7y agoThe information required to decode the data encoded on the glass is encoded on the glass. The AI/ML is apparently a testing mode, to ensure that someone who knows nothing about what is on the glass is able to extract video of the Superman movie from it. If the bootstrap section is good enough, the naive, untrained, know-nothing AI should be able to decode the movie. If it isn't good enough, the AI cranks for a long time and then puts Superman in a purple, orange, and green costume, and won't even know that those are all villain colors.
