Researchers at Open AI have taught artificial intelligence how to play Minecraft using only walkthrough videos. The training method was based on preliminary video training (Video PreTraining, VPT), ​​which made it possible to use a large amount of unlabeled data for this. To control AI, I used mouse and keyboard emulators.

At the first stage, the neural networks showed 2,000 hours of marked-up video with Minecraft gameplay. Here, the researchers demonstrated which buttons users pressed during the game. This allowed the system to learn to guess which buttons are pressed. At the second stage, the neural network has already viewed 70 thousand hours of unlabeled video (without data on the buttons being pressed). All entries were taken from open sources.

As a result, the neural network was able to learn not only to walk in the game world, but also to extract resources and create objects from them, run, swim, avoid obstacles, hunt animals and get food. AI has also learned to jump up and put blocks under the character to climb higher.

In the third stage, the researchers asked the users who took part in the project to help them. Players have created a new world in Minecraft, collected the necessary resources to start and crafted the essentials. All this was recorded on video, which was then shown by neural networks. Some have even built basic shelters, and the neural network has mastered this skill. The researchers used reinforcement learning, which allowed the AI ​​to eventually create a diamond pickaxe.

Scientists believe that the method of preliminary video training will allow you to quickly train neural networks for the necessary tasks, and will also allow you to train artificial intelligence to use the mouse and keyboard. The source codes of the project have already been published.

Previously, it was reported that Minecraft was completely completed in less than 2 minutes.

Like most home consoles, the Xbox Series X has been specifically designed to fit neatly into your living room. However, this was not enough for engineer Michael Pick, so he decided to create the world’s largest functional version of the Xbox Series X himself.

The author’s idea was partly inspired by a huge Microsoft refrigerator in the design of the console. However, the author wanted to keep the game features and copy the design exactly.

At the first stage, Peak had to create a wooden frame that mimics the body. Some parts had to be printed on a 3D printer and, mind you, glued. And on the rear panel of the giant console there are enlarged copies of real connectors – USB, audio and video output, network port, and so on.

Inside is the real Xbox Series X, and the button presses on the giant console are already transmitted to it. The final version is over 2 meters high, 1 meter wide and weighs 113 kg.

The giant Xbox Series X has already made it into the Guinness Book of Records. Michael donated it to the YMCA Youth and Adolescent Development Center in Atlanta, Georgia.

AOKZOE has announced a portable console of the same name, which is based on the 8-core Ryzen 6800U processor with 8 cores and 16 threads, as well as a maximum frequency of up to 4.7 GHz. Video processing is handled by 12-core RX 680M graphics based on the RDNA2 architecture. It is noted that the TDP of the hybrid processor will be from 14 to 28 watts, which will increase performance if necessary. The novelty will receive an 8-inch display based on an IPS matrix with a resolution of 1920 x 1200 pixels and a brightness of up to 380 nits.

Also announced are 16/32 GB of LPDDR5X-6400 RAM and an M.2 2280 slot for an SSD. Other features include a 48Wh battery and support for 100W fast charging, which will charge the battery in 1.5 hours. There are also stereo speakers, a microSD card reader, WiFi 6 and Bluetooth 5.0 adapters, and an optional docking station. On the back panel there is a folding stand. Separately, we note that the console supports both Windows and SteamOS.

In terms of performance, Cyberpunk 2077 on the console runs at 60 frames per second, Forza Horizon 5 – more than 100.

In addition, the console has RGB lighting, a gyroscope and a vibration motor. The novelty can be pre-ordered in July 2022, and deliveries will begin in September.

Earlier it was reported that Aya Neo is preparing a portable clamshell console called Flip. In technical terms, it is similar to AOKZOE.
