I remember that they had an impressive demo at the NIPS Deep Learning Workshop in December (probably a highlight for me and a few people I talked to afterwards) of a reinforcement learning agent playing Atari 2600 Games where the input consisted of an image that was fed through a Convolutional Neural Network. There is a paper on Arxiv that describes the approach ("Playing Atari with Deep Reinforcement Learning"[0]) b…

And what's interesting is they seem to be hiring a whole lot more [1]. If they are hiring a "growth hacker" they must be close to having something that's out in people's hands.

It seems that Google has now gone full Singularist. They jumped the shark when they hired Kurzweil.

I don't really understand the objective of those like Kurzweil. What do they see as the benefit of the singularity? Wouldn't a drastically more advanced intelligence just dwarf and dissolve any lesser intelligence that tried to meld with it? It would be complete ego death.

To be immortal is his main goal. Also have a look at any modern tech business and you will see more advanced intelligences serving less advanced ones (but good at schmoozing).

Here's a talk the founder gave in 2010 for Singularity U about combining neuroscience and machine learning. http://vimeo.com/17513841

He did mention the theory by Jeff Hawkins only very shortly. I think it is very relevant in this context because he gives high-level theory about how the neocortex works.

I can really recommend the book by him, On Intelligence, where he explains it quite understandable.

It explains why the brain has developed the different hierarchical layers of the visual system and how the same principle works everywhere in the neocortex. It's basically all predictions of time series at different abstraction levels.

I actually read this paper a couple weeks ago as part of a deep learning reading group that I co-run. While several of these authors are household names in the RL community, this paper was not actually that impressive to me. The only real "deep" learning here is that they used a GPU library and stochastic gradient descent to perform Q-learning updates on a network with 3 large hidden layers. It was an interesting app…

I suspect google wants to port this to their D-wav, probably sell API access to it. Rent an AI

The concept that AI will be many times human intelligence is result of biases. The microprocessors went from 4 bit to 64 or more bits and speed went from MHz to GHz. It may not be possible extrapolate the progress of microprocessors in the case of intelligence.

FYI, Shane Legg's theses was "Machine Super Intelligence". http://www.vetta.org/publications/

I'm really wondering where you have to go to grad-school for someone to approve a thesis that blatantly speculative.

I skimmed it and didn't think it was that bad - it's kind of interesting to see a thesis that allows reasonably informed speculation. I don't know enough about ML to say whether the core results are actually of any value.

The title is a bit much but it does say "The title of this thesis is deliberately provocative".
