The point is this brings us closer to demonstrating AI which is in some sense grounded in reality, as opposed to some kind of “Clever Hans” or Searle’s “Chinese Box.” The network has learned how to “imagine playing out a scenario” much like a human player might use his own mental model of the game to consider various strategies to attempt, perhaps with the real game.

That the network apparently has a mental model which is rich enough to simulate actual game play implies that it hasn’t just fit a static caricurature of the game which immediately breaks on an unseen move. That is, it has a non-trivial “conceptualization” of its environment which goes beyond simple pattern matching or nearest neighbor matching.

I've observed an increasing trend with modern AI research that A) It's no longer practical to incorporate into real products given the hardware costs for training and inference. In NLP, large transformer based models can easily occupy a 5 thousand dollar GPU at a paltry 50-60 words per second processing pace. B) The Research often demonstrates things that existing non-ML toolchains were already reasonable at doing wi…

It reminds me of older electric cars. They worked. They could get you around. But they did so at higher price, slower speeds, or other factors that a consumer wasn't willing to pay for. Thus they were regulated to novelty items that some work campuses would have and concept cars that would be shown from time to time. But eventually we reached the point where they are not only competitive, they may be positioned to fu…

The word you are looking for is "relegate", not regulate.

Does anyone know if we can combine knowledge from different domains when training to play games? Example: have a language model read pieces of text about the game, then feed the output of that into a model that's doing normal reinforcement learning. Maybe train them both at the same time?

The hope is that the model can combine inputs from different domains and generalize better.

I don’t think that’s the point of bleeding edge research. Pushing boundries != commercialization potential

Is there research in this field that is not commercially funded? That seems like a silly distinction in America.

> Trained on 50,000 episodes of the game Meanwhile an actual human will probably need only about 5 games to fully understand how the game works and reacts.

and how many games does a human need to transform into a pacman game playable by another human? ...lol

Do you really think nVidia is seriously advocating for using neural networks as the best way to write a PacMan clone? It's obviously just a proof of concept to demonstrate that GANs are sophisticated enough to learn certain categories of models.

Doing these cute demos is a double-edged sword. A fun and charming demo attracts attention by non-experts who can't see the wood for the trees.

In my field we make robots do a thing, say folding laundry, as an example of dextrous manipulation[1], and the popular conversation is about whether your laundry robot makes commercial sense and not about your novel grasping strategy and nifty motion planner that makes this sorta-possible for the first time. But everyone sees your video. Pros and cons.
