<br> <br><p><br> OpenAI, the artificial intelligence research group established by Elon Musk has taught an AI to play Minecraft nearly as well as humans. It only took about 70,000 hours of binge watching YouTube videos.<br></p><br><br> <br><br><br><br> <br><p><br> The blog post explains how researchers employed "Video PreTraining" (VPT) to train a neural network to play Minecraft. This included collecting 22,000 hours of data from people playing Minecraft. It also included exact keypresses, mouse movements, and raw video.<br></p><br><br> <br><br><br><br> <br><p><br> The researchers then trained an inverse dynamics (IDM), which predicted the future actions of the IDM at every stage of the videos. The "trained IDM" was shown more than 70,000 hours of Minecraft YouTube videos. The model was able copy the actions of the videos, such as cutting down trees to collect logs and making logs into crafting tables.<br></p><br><br> <br><br><br><br>
