Sagebrush posted:To me the most damning example is those papers with adversarial techniques where they apply a really subtle filter to the image and it tricks the algorithm. Like you start with an image of a turtle, and the machine recognizes it as a turtle, and then you apply a tiny convolution that affects 10% of the pixels in an almost undetectable way, and the algorithm is now certain that it's a picture of a gun. But it still looks like a turtle to you. wow, if this is true, you should contact the media. could be a big story

Cybernetic Vermin posted:a lot of ml research is dumb and bad (almost as dumb and bad as "tech visionaries" ideas of what ml can do), amounting to a phd student twiddling various parameters until a model seems to learn something, with no deeper analysis or insight. however, it is not right to view ml as having been bad for computer vision and natural language processing, not least ml is pretty simple, so it is not a hard tool to apply. is nlp still basically only done in english

i was looking around for some software to segment chinese text into words and it seems anything with more than 90% accuracy is like cutting edge university research algorithms the most popular one people in china actually use is so bad that i, a non native speaker, can find errors in basically every sentence i throw it at fart simpson fucked around with this message at 02:26 on Jan 4, 2020 |

idk maybe? i dont really know anything about linguistics but i do know you can give a chinese speaker a sentence and they can easily split it into component words. i mean it is more complicated in chinese because words can have sorta layered meanings in a way so maybe that means it's an artificial idea? but like, what seems to be the most popular tool that people in china use for this is a python library called jieba. i downloaded jieba and the very first sentence i threw into it was the first sentence from the chinese wikipedia article for "flower": 花是被子植物的繁殖器官 (flowers are the reproductive organs of angiosperms) if you asked any chinese reader they'd come up with: 花 / 是 / 被子植物 / 的 / 繁殖 / 器官 flowers / are / angiosperm / (posessive marker) / reproductive / organs jieba segmented this as the obviously nonsensical: 花是 / 被子植物 / 的 / 繁殖 / 器官 flowersare / angiosperm / (possessive marker) / reproductive / organs actually google translate does word segmentation too and also fails even worse than jieba on this sentence although it gets the overall meaning correct so i guess i see your point about the statistical methods thing

yeah i was surprised too. i think there's probably some settings i can adjust because i found a javascript reimplementation of jieba that gets this sentence correct. but yeah i'm playing around with a dataset i found of 300k news articles written in chinese and just this usage of "是" as a verb makes up 1% of the entire body of text of the dataset. it's probably either the 1st or 2nd most commonly used verb in chinese. google's segmenter got that word correct but totally butchered the segmentation of angiosperms into 3 separate words which would translate as like, "blanket seed plants" or something which i guess is kinda what angiosperms are anyway? especially because the word 被 can be a noun meaning blanket or a verb meaning to cover
