Converting Minecraft worlds to photorealistic ones using neural networks

Researchers from NVIDIA and Cornell University made GANcraft: GANcraft aims at solving the world-to-world translation problem. Given a semantically labeled block world such as those from the popular game Minecraft, GANcraft is able to convert it to a new world which shares the same layout but with added photorealism. The new world can then be rendered from arbitrary viewpoints to produce images and videos that are both view-consistent and photorealistic....

When you don’t own your face

For The New York Times, Kashmir Hill describes the implications of facial recognition becoming a thing that everyone just has: Retail chains that get their hands on technology like this could try to use it to more effectively blacklist shoplifters, a use Rite Aid has already piloted (but abandoned). In recent years, surveillance companies casually rolled out automated license-plate readers that track cars’ locations, which are frequently used to solve...

Public agencies using facial recognition software without oversight

An anonymous source supplied BuzzFeed News with usage data from Clearview AI, the facial recognition service that was banned by many police departments nationwide. Many agencies still used and/or tried it: The data, provided by a source who declined to be named for fear of retribution, has limitations. When asked about it in March of this year, Clearview AI did not confirm or dispute its authenticity. Some 335 public entities...

Technopolitics of the U.S. census

Dan Bouk and Danah Boyd wrote an essay on the data infrastructure and politics behind the decennial census: Like all infrastructures, the U.S. decennial census typically lives in the obscurity afforded by technical complexity. It goes unnoticed outside of the small group of people who take pride in being called “census nerds.” It rumbles on, essentially invisible even to those who are counted. (Every 10 years, scores of people who...

Teaching statistical models with wine tasting

For The Pudding, Lars Verspohl provides an introduction to statistical models disguised as a lesson on finding good wine. Start with a definition of wine, which becomes a way to describe it with the numbers. Define what makes a wine good. Find the wines that look closer to that definition. Tags: modeling, Pudding, wine

Statistical limits

Reviewing Deborah Stone’s Counting and Tim Harford’s The Data Detective, Hannah Fry discusses the usefulness of data and its limitations for The New Yorker: Numbers are a poor substitute for the richness and color of the real world. It might seem odd that a professional mathematician (like me) or economist (like Harford) would work to convince you of this fact. But to recognize the limitations of a data-driven view of...

Inadequate hate crime statistics

For ProPublica, Ken Schwencke reports on a poor data system that relies on local law enforcement to voluntarily enter data: Local law enforcement agencies reported a total of 6,121 hate crimes in 2016 to the FBI, but estimates from the National Crime Victimization Survey, conducted by the federal government, pin the number of potential hate crimes at almost 250,000 a year — one indication of the inadequacy of the FBI’s...

Rising number of anti-Asian attacks

Russell Jeung, chair of the Asian American Studies Department at San Francisco State University, on NPR about the recent rise: What we’ve discovered isn’t that we’ve just had a spike, but we’ve had a surge over the entire year last year with COVID-19 and with the president’s political rhetoric in the last administration. We now have over 3,000 incidents and hate-filled incidents where people are tormenting Asian Americans. I can’t...

DeepTomCruise breakdown

Chris Ume, with the help of Tom Cruise impersonator Miles Fisher, created highly believable deepfakes of Tom Cruise and posted the videos to TikTok. Ume showed the breakdown of the arduous process of training the A.I. model and editing each frame. The Verge talked to Ume more about the process: “You can’t do it by just pressing a button,” says Ume. “That’s important, that’s a message I want to tell...
