Intelligence is a key concept in the quest for artificial intelligence, and more generally the singularity. Remarkably, relatively little work has gone into developing general, encompassing and theoretically founded definitions of intelligence for machines. This leaves us without a clear foundation for either theoretical research or developing empirical measures of progress. In this talk I outline the major perspectives on the nature of intelligence and some of the informal definitions that have been put forward. I then sketch the main ideas behind the universal intelligence measure. This is a formal definition of intelligence based on Hutter's AIXI model of theoretically optimal machine intelligence. Based on this a number of researchers, including myself, are developing practical tests of machine intelligence. I describe some of the challenges faced when doing this and share some recent results from testing various artificial agents. Might we soon be able to measure our progress towards machine intelligence?
Here is a 2007 paper by Shane Legg on Universal Intelligence (47 pages
He is reviewing the computations per second from the best supercomputers by year. He notes that it is slightly curving upward on a log graph. It is projected that we have exaflops around 2018 and 100 exaflops by 2025.
But he wants to see machine intelligence against the year.
Will you use a human model of intelligence or a more ideal or normative model of intelligence
Does it have to have thought, emotions, etc...
Or is it just external behaviors (quack and walk like a duck)
Human Ideal Internal niel block Aristotal Properties External Turing Will look Properties here
Theese are different questions not just different answers.
Look at ideal external because if it cures cancer then don't care how it does it.
But if you cared about uploading then the Internal human measure would matter.
