A Human-level Intelligence (AGI) Machine is an intelligent machine with a system capability that approximates human-level intelligence.

    • Artificial general intelligence (AGI) is the intelligence of a machine that could successfully perform any intellectual task that a human being can. It is a primary goal of artificial intelligence research and a common topic in science fiction and futurism. Artificial general intelligence is also referred to as "strong AI",[1] "full AI" [2] or as the ability of a machine to perform "general intelligent action". [3] Some references emphasize a distinction between strong AI and "applied AI" [4] (also called "narrow AI"[1] or “weak AI[5] ): the use of software to study or accomplish specific problem solving or reasoning tasks. Weak AI, in contrast to strong AI, does not attempt to perform the full range of human cognitive abilities.





    • QUOTE: What’s Missing
      • More autonomous learning, unsupervised learning
      • Discovering the underlying causal factors
      • Model-­‐based RL which extends to completely new situations by unrolling powerful predictive models which can help reason about rarely observed dangerous states
      • Sufficient computational power for models large enough to capture human-­‐level knowledge
      • Autonomously discovering multiple time scales to handle very long-­‐term dependencies
      • Actually understanding language (also solves generating), requiring enough world knowledge / commonsense
      • Large-­‐scale knowledge representation allowing one-­‐shot learning as well as discovering new abstractions and explanations by ‘compiling’ previous observations

    • QUOTE: … a fundamental error in not distinguishing the difference between the very real recent advances in a particular aspect of AI, and the enormity and complexity of building sentient volitional intelligence. … Why so many years? As a comparison, consider that we have had winged flying machines for well over 100 years. But it is only very recently that people like Russ Tedrake at MIT CSAIL have been able to get them to land on a branch, something that is done by a bird somewhere in the world at least every microsecond. Was it just Moore’s law that allowed this to start happening? Not really. It was figuring out the equations and the problems and the regimes of stall, etc., through mathematical understanding of the equations. …

      … If we are spectacularly lucky we’ll have AI over the next thirty years with the intentionality of a lizard, and robots using that AI will be useful tools.



    • Artificial General Intelligence (AGI) is an emerging field aiming at the building of “thinking machines", that is, general-purpose systems with intelligence comparable to that of the human mind. While this was the original goal of Artificial Intelligence (AI), the mainstream of AI research has turned toward domain-dependent and problem-specific solutions]; therefore it has become necessary to use a new name to indicate research that still pursues the "Grand AI Dream". Similar labels for this kind of research include “Strong AI", “Human-level AI", etc.

      The problems involved in creating general-purpose intelligent systems are very different from those involved in creating special-purpose systems. Therefore, this journal is different from conventional AI journals in its stress on the long-term potential of research towards the ultimate goal of AGI, rather than immediate applications. Articles focused on details of AGI systems are welcome, if they clearly indicate the relation between the special topics considered and intelligence as a whole, by addressing the generality, extensibility, and scalability of the techniques proposed or discussed.

      Since AGI research is still in its early stage, the journal strongly encourages novel approaches coming from various theoretical and technical traditions, including (but not limited to) symbolic, connectionist, statistical, evolutionary, robotic and information-theoretic, as well as integrative and hybrid approaches.
