Re: Where will artificial general intelligence come from?

I gave this talk a while ago to a small group of attendees. It was not recorded (I saw some ask below). It's based on a document I wrote a while ago called "You suck at writing AI" (never published). The basic argument was that people are comically inadequate at writing complex code. You can't write the code to detect a cat in an image and the correct thing to do is to give up, write down an objective that measures t…

Plot twist: figuring out that objective function may prove as intractable as the original problem! We'll need an objective function writing objective function, and then it's turtles all the way down.

The main objective function in nature is very simple though: maximize the number of copies of your genes. Such an objective enforced in a resource-constrained multi-agent world (as suggested in the slides) could really lead to quite complex sub-objectives which may as well lead to general intelligence. For example, if each agent can process information and perform work, it follows that individuals that have better cooperative abilities also have a larger reproductive success. Cooperation is, however, extremely complex: It requires communication, identification of other individuals, establishment of trust, early detection of betrayal etc. The necessity for modeling the actions of other agents alone provides plenty of correction signals toward general intelligence because modelling other agents is such a difficult task.

I don't know that "maximize descendants of self" is necessarily right though. It seems like a better statement might be "maximize the development of complexity in the universe". Just as an example, lots of people choose to forgo having children to focus on contributing to the universe in other ways (myself included). This isn't just a self-centered drive for fame/wealth/etc either, as many people pursue their quests in poverty/obscurity, and some even choose anonymity.

Any thoughts on what role novelty search might play? ("Why Greatness Cannot Be Planned: The Myth of the Objective" by Kenneth Stanley)

Well, for biological organisms, it's all about reproductive success. I mean, what exits today reflects what managed to reproduce, and how well. Overall, that has created lots of complexity. But that's just because there are so many niches and ways to be successful in them.

What you say about people reflects cooperative behavior that drives reproductive success for shared gene complexes.

I don't think that we'd want that sort of AI, as a competitor. But if we could become one, that would be cool.

Background: I did AI and Philosophy of Mind in undergrad, an MSc focused on ALife, then a PhD at Yale under a Macarthur Fellow who developed the theoretical framework for the 'evolution of Evolvability' where I worked on computational evolutionary biology. I can say we're not going to blindly brute force our way forward, but instead we'll need to reverse engineer nature's core algorithms to generate hard AI. Every ti…

Don't know why you feel so compelled to give your background while writing an anonymous comment on the internet. It only makes me suspect your argument doesn't hold up without some expectation to respect your authority. All the theory in the world is irrelevant until it you can apply it to predict something new -- its almost trivial to create a theory that describes some phenomenon accurately, after-the-fact. See the tremendous bifurcation in physics with regards to string theory. Similarly there are loads of academics in various fields claiming to have been the origins of artificial intelligence.

The presentation briefly mentioned simulating the brain, but I think what's more likely to succeed is mimicking the mind at a high level of abstraction (i.e. a level we can study with introspective or even linguistic methods rather than neuroscience). There's some precedent for this with projects like Soar and ACT-R (and even some recent interest from mathematicians [1]). IMHO this kind of methodology could be pushed much further.

Actually convnets were inspired by Fukushima's Neocognitron, which was itself inspired by visual cortex.

> Actually convnets were inspired by Fukushima's Neocognitron, which was itself inspired by visual cortex. That doesn't contradict what I wrote. ConvNets require the synchronization of weights between neurons, which is not considered to be biologically plausible. Some aspects of the architecture (the receptive fields, in this case) may well be plausible, with the complete architecture still implausible.

You're focusing too much on the implementation details and assuming that because they're different that it's not equivalent. The secret sauce here is that network topology (and threshold rules), not the implementation details, are largely what determine the functional properties of that network. Show an electrical engineer the circuit diagram of a 4 bit adder and they'll know it's function immediately. Artificial Neural Networks and Artificial Gene Regulatory Networks are the same. The problem with ANNs is that we fail to see the circuitry driving the function because we assume that every w_ij != 0 is functionally relevant. Once you start to strip away non-spurious interactions you start to see topological patterns. I did a lot of work on this problem -- this is not an uneducated guess.
