AI who plays Minecraft like an expert

Capabilities Artificial Intelligence (AI) Never cease to amaze anyone. In recent months, it has been possible to see everything, from engineer The Google talk to chat bot Even crazy creations DALL-E Mini.

Now, as if that wasn’t enough, model Open AI I learned to play Maine Craft Watch videos YoutubeAnd it works very well.

The company explains that a model trained to play Minecraft has abilities beyond the game’s basic survival missions, such as Swimming, hunting and cooking animals. He even mastered the “column jump” technique, which allowed him to create a temporary block to reach higher places.

Artificial intelligence training to learn how to play

While training different AI systems for different tasks has been appreciated before, such as driving a automaticAnd the Researchers had to overcome many challenges to train an AI model in game open world

First, they need a lot of data, Which can be easily found on YouTube Because Minecraft is one of the most popular games.

However, the videos uploaded to YouTube by game lovers show what they are doing in the game, No how do they do it. Therefore, it is inconvenient for artificial intelligence, which does not know what to do to perform certain actions. in this meaning, The researchers applied a new technique called video pre-training (VPT).

Instead of using “tags” to classify a large set of data, the researchers focused on a small portion. So, in this section, It included important data such as keystrokes and mouse movements. With this, they trained a Inverse Dynamic Model (IDM) Able to predict the next action.

So, with this foreknowledge, They can train the model with 70,000 hours of unclassified video. That is, they took the time to teach AI first Game Basics So that he learns to identify them himself and Perform complex operations that players usually perform in Minecraft, Like the ones mentioned above. Similarly, you can also make tools with diamonds.

“Learning how to cut trees to harvest wood and turn that wood into a workbench is nearly impossible to achieve through reinforcement learning from scratch,” Confirmed by OpenAI After your last survey.

The company says that the fact that these developments may extend beyond the world of video games, It can be useful in other situations, such as learning to use a the computer“.

The startup Sonantic has developed a voice that has some subtle details that make it more natural in the way of speaking.

They pointed out to The Verge that the key is Incorporate non-verbal sounds into your audio; Train their AI models to recreate those small models take a breath (Small sarcasm and half-hidden laughter) That give real speech its character of biological originality.

In this project, they chose “love as a general theme”, so the AI ​​flirts with everyone who interacts with it. Those who “talk” to the AI ​​indicate that when they first hear it, it sounds like a human voice, although The nuances of what is a file RobotAs they say, “I left strange spaces between certain words and slight artificial wrinkles in the pronunciation.”

In a company video posted on YouTube titled “What’s her secret?” (What’s your secret?) Who are you listening to A woman who claims to be in love, however, later asks if she knows that she was not born and will never die, that she can still be loved (by listener).

At that moment, the image of the young woman is changed and voice commands appear, interrupted by expressions such as “breathing” or “laughter”, aspects that give her some nature.
