Here is a quote from Marcus Hutter
which I think is an excellent definition of what it means to be an agent:
“”Solomonoff
derived an optimal way of predicting
future data, given
previous perceptions, provided the data is sampled from a computable
probability distribution. AIXI extends this approach to an optimal decision
making agent embedded in an unknown environment. The main idea is to replace
the unknown environmental distribution μ in the Bellman equations by a suitably
generalized universal Solomonoff distribution . The state space is the space of
complete histories. AIXI is a universal theory without adjustable parameters, making
no assumptions about the environment except that it is sampled from a
computable distribution. From an algorithmic complexity perspective, the AIXI model
generalizes optimal passive universal induction to the case of active agents.Solomonoff

Now that sounds like an implementable
agent: an agent that could be emulated in software completely.
In our emerging self interest ontology, I
believe we can define an agent in one semantically precise sentence. Perhaps
the sentence :
“an agent pursues
self interest as the agent herself defines it.”
will do the job.
Then we need a decision making engine just
like the one AIXI emulates, or perhaps other choices TBD.
How is the plan doing so far?
Suggestions, corrections, critiques,
dialogs, whatever very much appreciated.
