Online videos are a vast and untapped source of training data—and OpenAI says it has a new way to use it.
OpenAI has built the best Minecraft-playing bot yet by making it watch 70,000 hours of video of people playing the popular computer game. It showcases a powerful new technique that could be used to train machines to carry out a wide range of tasks by binging on sites like YouTube, a vast and untapped source of training data.
The Minecraft AI learned to perform complicated sequences of keyboard and mouse clicks to complete tasks in the game, such as chopping down trees and crafting tools. It’s the first bot that can craft so-called diamond tools, a task that typically takes good human players 20 minutes of high-speed clicking—or around 24,000 actions.
The result is a breakthrough for a technique known as imitation learning, in which neural networks are trained to perform tasks by watching humans do them. Imitation learning can be used to train AI to control robot arms, drive cars, or navigate web pages. Read More

This AI Time Machine Transforms You Into A Historical Figure From Any Era
If your social media profile photo needs some zhuzhing up, this AI image generator can turn your selfies and portraits into timeless works of art.
Apps that are designed to produce highly creative imagery through artificial intelligence (AI) are certainly having a moment these days, as another one designed to turn users into prominent people from the past is making the rounds online. Most AI art generators use text-to-image technology that requires user input to determine the artistic direction of rendered photographs. AI art generation is now a mainstay in the zeitgeist, thanks to the likes of DALL-E, an open-source project that inspired many others, which people started using to produce hilarious memes.
Soon after DALL-E’s rise to fame, more platforms that cater to producing hyperrealistic images from descriptive text prompts, including Midjourney and Stable Diffusion, came out of the woodwork and have since attracted sizable user bases. … AI Time Machine is an entertaining new feature that’s currently free to try on MyHeritage, an online genealogy platform. It works by taking a collection of photos depicting a single person and turning them into themed portraits seemingly captured from different points in history. Read More
