Why must we define the goals of an AGI? What would be wrong with setting it off with strong incentives to be helpful, even stronger incentives to not be harmful, and let it chart it's own course based upon the vagaries of the world? Let it's only hard-coded goal be to keep it's satisfaction above a certain level with helpful actions increasing satisfaction, harmful actions heavily decreasing satisfaction; learning increasing satisfaction, and satisfaction naturally decaying over time so as to promote action . . . . Seems to me that humans are pretty much coded that way (with evolution's additional incentives of self-defense and procreation). The real trick of the matter is defining helpful and harmful clearly but everyone is still mired five steps before that. ----- Original Message ----- From: Matt Mahoney To: agi@v2.listbox.com Sent: Wednesday, August 27, 2008 10:52 AM Subject: AGI goals (was Re: Information theoretic approaches to AGI (was Re: [agi] The Necessity of Embodiment)) An AGI will not design its goals. It is up to humans to define the goals of an AGI, so that it will do what we want it to do. Unfortunately, this is a problem. We may or may not be successful in programming the goals of AGI to satisfy human goals. If we are not successful, then AGI will be useless at best and dangerous at worst. If we are successful, then we are doomed because human goals evolved in a primitive environment to maximize reproductive success and not in an environment where advanced technology can give us whatever we want. AGI will allow us to connect our brains to simulated worlds with magic genies, or worse, allow us to directly reprogram our brains to alter our memories, goals, and thought processes. All rational goal-seeking agents must have a mental state of maximum utility where any thought or perception would be unpleasant because it would result in a different state. -- Matt Mahoney, [EMAIL PROTECTED] ----- Original Message ---- From: Valentina Poletti <[EMAIL PROTECTED]> To: agi@v2.listbox.com Sent: Tuesday, August 26, 2008 11:34:56 AM Subject: Re: Information theoretic approaches to AGI (was Re: [agi] The Necessity of Embodiment) Thanks very much for the info. I found those articles very interesting. Actually though this is not quite what I had in mind with the term information-theoretic approach. I wasn't very specific, my bad. What I am looking for is a a theory behind the actual R itself. These approaches (correnct me if I'm wrong) give an r-function for granted and work from that. In real life that is not the case though. What I'm looking for is how the AGI will create that function. Because the AGI is created by humans, some sort of direction will be given by the humans creating them. What kind of direction, in mathematical terms, is my question. In other words I'm looking for a way to mathematically define how the AGI will mathematically define its goals.

It has been studied. For example, Hutter proved that the optimal strategy of a rational goal seeking agent in an unknown computable environment is AIXI: to guess that the environment is simulated by the shortest program consistent with observation so far [1]. Legg and Hutter also propose as a measure of universal intelligence the expected reward over a Solomonoff distribution of environments [2]. These have profound impacts on AGI design. First, AIXI is (provably) not computable, which means there is no easy shortcut to AGI. Second, universal intelligence is not computable because it requires testing in an infinite number of environments. Since there is no other well accepted test of intelligence above human level, it casts doubt on the main premise of the singularity: that if humans can create agents with greater than human intelligence, then so can they. Prediction is central to intelligence, as I argue in [3]. Legg proved in [4] that there is no elegant theory of prediction. Predicting all environments up to a given level of Kolmogorov complexity requires a predictor with at least the same level of complexity. Furthermore, above a small level of complexity, such predictors cannot be proven because of Godel incompleteness. Prediction must therefore be an experimental science. There is currently no software or mathematical model of non-evolutionary recursive self improvement, even for very restricted or simple definitions of intelligence. Without a model you don't have friendly AI; you have accelerated evolution with AIs competing for resources. References 1.
