Pandemic migrations Posted: 20 Apr 2021 10:39 AM PDT With the restrictions of the pandemic, you might expect an unusually big wave of people leaving cities for more open space. Using USPS’s change of address data, Jed Kolko, Emily Badger and Quoctrung Bui, for NYT’s The Upshot, show that this was not quite the case. This surprised me, because I live in a suburban area that saw a flux of home buyers, which made prices approach ridiculous ranges. I wonder what in- and out-migration look like separately, on relative and absolute scales. Tags: coronavirus, migration, pandemic, Upshot

Converting Minecraft worlds to photorealistic ones using neural networks Posted: 20 Apr 2021 02:25 AM PDT 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. This is impressive, but what amazes me more is that Minecraft is still very much a thing after all these years. Tags: Minecraft, neural network, photorealistic
