"Apart from biases in the training databases, it's hard to know how well face-recognition systems actually perform in the real world, in spite of recent gains. Anil Jain, a professor of computer science at Michigan State University who has worked on face recognition for more than thirty years, told me, "Most of the testing on the private venders' products is done in a laboratory environment under controlled settings. In real practice, you're walking around in the streets of New York. It's a cold winter day, you have a scarf around your face, a cap, maybe your coat is pulled up so your chin is partially hidden, the illumination may not be the most favorable, and the camera isn't capturing a frontal view.""

"Where the researchers struck gold was by realising that a large (but not overly large pair of glasses) could act to "change the pixels" even in a real photo. By picking a pair of "geek" frames, with relatively large rims, the researchers were able to obscure about 6.5% of the pixels in any given facial picture. Printing a pattern over those frames then had the effect of manipulating the image."

" "Why isn't my face being detected? We have to look at how we give machines sight," she said in a TED Talk late last year. "Computer vision uses machine-learning techniques to do facial recognition. You create a training set with examples of faces. However, if the training sets aren't really that diverse, any face that deviates too much from the established norm will be harder to detect.""

"The results may seem similar to what you'd get if you'd searched WebMD, Mayo Clinic, etc. The difference is that Dr. A.I. pulls in many more data points than those sites do, then combines artificial intelligence with a massive database to pinpoint the most likely results in your specific case. It doesn't just find all possible ailments and list them for you to explore further on your own."

"Game players-like drivers-often have to reach conclusions without full understanding of what the other players-or drivers-are doing. So more researchers are applying game theory to train self-driving cars how to act in uncertain situations."

"Activists from Fight for the Future prowled the halls of Congress in "jumpsuits with phone strapped to their heads conducting live facial recognition surveillance" to "show why this tech should be banned.""

"How do you maximize food production and prevent waste in your supply chain at a time when climate change and a growing global population are placing an increasing strain on resources?  According to Israeli startup Blue Circle, you do it in the same way you protect your technology from hackers: with artificial intelligence, machine learning and huge amounts of data. "

"In some sense, GPT is like a glorified version of cut and paste, where everything that is cut goes through a paraphrasing/synonymy process before it is paste but together-and a lot of important stuff is sometimes lost along the way. When GPT sounds plausible, it is because every paraphrased bit that it pastes together is grounded in something that actual humans said, and there is often some vague (but often irrelevant) relationship between.. At least for now, it still takes a human to know which plausible bits actually belong together."

"The debate is whether the ideas noted in an essay or paper come from the student, while the tool can only take credit for the grammar and mechanics of the writing but not the critical thinking. The College Board, which administers Advance Placement (AP) courses, prohibits the use of ChatGPT under any circumstances. On its website, the agency notes, "Like educators across the country, AP teachers are confronting the implications of ChatGPT and other tools.""

"Exclusive: OpenAI Used Kenyan Workers on Less Than $2 Per Hour to Make ChatGPT Less Toxic"

"ChatGPT will see you now. The artificial intelligence tool may be better than a doctor at following recognised treatment standards for depression, and without the gender or social class biases sometimes seen in the physician-patient relationship, a study suggests. The findings were published in Family Medicine and Community Health, the open access journal owned by British Medical Journal. The researchers said further work was needed to examine the risks and ethical issues arising from AI's use."

"In combining these factors, we arrive at a civilization built upon a technological infrastructure that we fundamentally cannot understand. The same systems that promise us technological emancipation put the whole of society at risk. I vaguely recall a wise man once saying that only the fool builds his house upon sand. And so, how can a society maintain itself if the stones of its foundation are black boxes? Before we answer this question, let's examine the current state of affairs."

"Actually, ChatGPT was freaking out in many ways yesterday, but one recurring theme was that it would be prompted with a normal question - typically something involving the tech business or the user's job - and respond with something flowery to the point of unintelligibility. For instance, according to an X post by architect Sean McGuire, the chatbot advised him at one point to ensure that "sesquipedalian safes are cross-keyed and the consul's cry from the crow's nest is met by beatine and wary hares a'twist and at winch in the willow.""

"Sara needed some chocolate - she had had one of those days - so wandered into a Home Bargains store. "Within less than a minute, I'm approached by a store worker who comes up to me and says, 'You're a thief, you need to leave the store'." Sara - who wants to remain anonymous - was wrongly accused after being flagged by a facial-recognition system called Facewatch."
