This sounds ambitious. I wonder if they can also address the following problem. Currently, deep learning toolkits need thousands of training images to classify images of, e.g., dogs and cats. A human, in contrast, could learn the difference between a dog and a cat by looking just at a single example (or perhaps a few). So right now, deep learning is too much "simple" pattern matching, and too little real "AI".

Anyone who had raised a child would tell you that, a human, requires years of training to learn the difference between a dog and a cat, by looking countless examples.

Of course, the disparity between deep neural nets and human brains remains unknown. A human learns the difference between a cat and a dog, while at the same time, learns so many different things, yet a neural net only learns the difference between a cat and a dog. We don't know how much we don't know.

From the paper:

DeepMind Lab is built on top of id software’s Quake III Arena (id software, 1999) engine using the ioquake3 (Nussel et al., 2016) version of the codebase, which is actively maintained by enthusiasts in the open source community. DeepMind Lab also includes tools from q3map2 (GtkRadiant, 2016) and bspc (bspc, 2016) for level generation. The bot scripts are based on code from the OpenArena (OpenArena, 2016) project.

Why is there such low activity on this thread vs the OpenAI thread?

One is free and open, with many different software options and partnerships.

The other is free and open, but governed by a corporation, with a single software option and no partnerships.

Earlier quoted context omitted.

which I always assume is at least partly implicit in these ambitious projects No serious researcher is even contemplating that problem yet, except as a thought experiment. These projects are more about working out how to work out what questions to ask to direct research which might lead to more generalised AI.

Alright thanks. Do you want to recommend reading regarding the state of the art? Technical papers Ok.

SOTA on what specifically? DeepMind is probably the world leader on reinforcement learning, so https://deepmind.com/research/publications/ isn't a bad place to start.

I find it interesting that they specify "3D vision from a first person viewpoint". Can somebody explain to me the significance of first person viewpoint vs 3rd person (or other)?

I assume it is because a first person perspective would have more applications in the field of robotics - e.g. twin forward-facing cameras on something like Boston Robotics robotic dog.

When they say that they're based in the King's Cross Knowledge Quarter what they mean is that they will share the Google's office which don't exist yet.

I think I will never understand the sort of mindset where you just say things regardless of whether you know them to be true. https://www.google.com/maps/place/Google+UK/@51.5246616,-0.1...

DeepMind were acquired by Google but are still somewhat separate and are in a different building to that one without any Google logos on.

I'm not convinced that a person who's never seen animals before could tell the difference between all future dogs and cats from a single training example. Humans draw upon a lifetime of learning and experience to achieve this 'one shot learning' capability. If you take a pre-trained convnet (which, by analogy is like a person who has had 'life experience' of looking at objects), and extract activations for unseen obj…

I'd argue that it's less beneficial to learn new categories as it is to simply recognize when categories differ between samples.

For example, with bears -- I personally know of black bears and polar bears. I can be a little more detailed with fish but with dogs there are dozens of "different" [easily recognizable] types within the same category of "dog".
