For object recognition, this meant photos with target items outlined and labeled, usually by a person (for instance, labeling a вЂњcupвЂќ), and for language, sources of reasonably well-written text. These algorithms required not only data in quantity, but quality. Computer scientists found that in many cases deep learning scaled: The more data they used, the more accurate it got. To achieve better and better results, deep learning algorithms needed bigger and bigger datasets - the bigger, the better. By 2015 that figure topped 95 percent - surpassing that of humans, at least in laboratory settings - and people soon found myriad applications for the new approach. Using a souped-up version of machine learning called deep learning, the team achieved an 85 percent accuracy rate, 10 percentage points higher than the previous yearвЂ™s top team. In 2012, a team of University of Toronto researchers trounced all comers in an object recognition contest based on the AI dataset ImageNet, which had been created by Princeton researchers just a few years before. W hile machine learning dates back to the 1940s, it only really took off in the past decade. And they are looking at systemic reforms in data collection, combined with alternative techniques that use less data, to offer a potential exit ramp. Some computer scientists are asking whether the brute force approach of compiling ever-larger datasets is necessary to sustain machine learning, and if the expansion can continue indefinitely. ThatвЂ™s hugely problematic because it encourages the cheapest, laziest possible gathering of data.вЂќ вЂњThereвЂ™s this race to have bigger datasets with more and more parameters,вЂќ said Daniel Leufer, a Brussels-based policy analyst at the digital rights organization Access Now. But many other large public datasets remain online, and, in general, a bigger-is-better imperative remains. Pushed by outside groups calling for more ethical data collection and by negative media attention, the industry has only recently begun to examine these problems - sometimes by pulling datasets offline. вЂњYouвЂ™ve created this system in industry that rewards shady practices, rewards people stealing data from the internet or scraping it from social networks and creating products with no standard of how well they work,вЂќ said Liz OвЂ™Sullivan, chief executive of Parity, a startup that provides companies with tools to build responsible AI systems. As machine learning datasets expand, they increasingly infringe on privacy by using images, text, or other material scraped without user consent recycle toxic content and are the source of other, more unpredictable biases and misjudgments. Some of those problems are well known, such as the demographic skew in many facial recognition datasets toward White, male subjectsВ - a bias passed on to the algorithms.Д«ut there is a broader data crisis in machine learning. But as the applications grow more varied and complex, the rising demand for data is exacting growing social costs. To learn, algorithms need massive datasets. The approach is increasingly used by businesses and government agencies in addition to facial recognition systems, itвЂ™s behind FacebookвЂ™s news feed and targeting of advertisements, digital assistants such as Siri and Alexa, guidance systems for autonomous vehicles, some medical diagnoses, and more.

Machine learning reveals patterns in data - such algorithms learn, for example, how to identify common features of вЂњcupnessвЂќ from processing many, many pictures of cups. The problems originate in the mundane practices of computer coding. Related How Artificial Intelligence Could Help Doctors Around the same time, people reported that they could no longer access Diversity in Faces, a dataset of more than a million facial images collected from the internet, released at the beginning of 2019 by a team of IBM researchers.ДЄll together, about a dozen AI datasets vanished - hastily scrubbed by their creators after researchers, activists, and journalists exposed an array of problems with the data and the ways it was used, from privacy, to race and gender bias, to issues with human rights. In June, Duke University researchers withdrew their multi-target, multi-camera dataset (DukeMTMC), which consisted of images taken from videos, mostly of students, recorded at a busy campus intersection over 14 hours on a day in 2014. In April, it was MicrosoftвЂ™s MS-Celeb-1M, consisting of 10 million images of 100,000 peopleвЂ™s faces - many of them celebrities, as the name suggests, but also many who were not public figures - harvested from internet sites. Such collections - typically gigabytes of images, video, audio, or text data - are the foundation for the increasingly ubiquitous and profitable form of AI known as machine learning, which can mimic various kinds of human judgments such as facial recognition. I n the spring of 2019, artificial intelligence datasets started disappearing from the internet.
