Concept Acquisition in Icarus
Concept Acquisition in Icarus
Icarus can learn from experience simply because it stores all of its
experiences in its long term
memory. The concept
hierarchy will be modified to reflect all perceived objects,
places, generated plans, and executed actions. For example, for each
abstract problem LABYRINTH stores:
- the probability that a particular operator will be useful in
solving it;
- the probability that a subplan or operater will be
abandoned before the whole plan is finished;
- the probability that a
given state will, indeed, occur during the execution of a plan.
All these probabilities will help the planner next time it meets a
problem that is an instance of the abstract problem. They will also
help the execution system in determining when it is safe to perform
the atomic actions.
