NVidia’s graphic cards are well known, but there is some significant artificial intelligence work. Nvidia Researchers taught an AI program to recreate Pac-Man’s game simply by watching it play. The coding is not involved; the program has no pre-rendered images. In addition to the corresponding controller inputs, the AI model simply provides the visual data on the game to function and then frames it from this information. The resulting game is human playable, and Nvidia says it is going to be published online soon.

The AI edition is definitely not a complete fax however. The imagery is blurry, so it does not appear that the AI is able to capture the exact actions of the visions of the game. Each of them has a specific personality system that determines its motion. Yet Pac-Man is all about his simple dynamic: swallowing pellets, resisting nightmares and not dying. NVidia’s Rev Lebaredian, vice president for simulation technologies, told the journalists in a meeting, “It knows all these things just by watching.” It’s about how a human programmer can see a lot of Pac-Man videos on YouTube and conclude and recreate what the rules of the games are.


Nvidia informs us how artificial intelligence can be used in the future for game production. Developers can join and use their work to create improvements or to build new stages. Developers can use their work. Sanja Fidler, Director of the Nvidia Development Lab in Toronto, told reporters that she will “give developers additional control by [letting] various games together.”

GameGAN is the software which recreated Pac-Man. GAN is an architecture widely used in machine learning that reflects the generative net of adversaries. A GAN is built upon two halves of working. In the first half of the GAN the data is repeated, and in the second half this is applied to the initial source. If they do not correlate, the data generated are rejected and the generator tweaks and submits its work again.

AI has historically been used to create virtual environments such as video games. But the researchers of Nvidia have introduced several new aspects, including a “memory module,” which enables the system to store an inner map of the gaming world. It leads to further coherence in the realm of sports, a crucial element of recreating Pac-Man labyrinths. These are also programmed to distinguish the static elements of the game world (such as the labyrinth) from dynamic ones (such as spirits) that match the company’s goal of using AI to create new stages.

David Ha, an AI researcher at Google, who worked on related ventures, he also told that it, was really fascinating. Previous teams attempted to replicate game environments using GANs, Ha said, “But this was the first team to produce good results from what I learned.” All in all, a very interesting paper, and I am looking forward with this approach to future developments, said Ha.

However, certain elements of the method still need modification, which show that artificial intelligence is especially vulnerable as new tasks are encountered. Fidler told reporters that GameGAN would be conditioned in about 50,000 episodes to replicate Pac-Man. It was not possible to get the data from people in the games, so the team used an AI agent to produce the data. The AI agent was so good at the game, sadly, that it never died.
