Abstract

Methods and apparatus to incorporate user feedback during planning. In one embodiment, first and second plans are generated for which user feedback is obtained and used to generate a revised plan.

Claims

1. A method, comprising:

generating a first plan having a series of actions;

outputting the plan to enable a user to perceive the plan;

receiving feedback from the user on the plan;

generating a revised plan based upon the first plan and the feedback from the user.

2. The method according to claim 1, wherein the user feedback includes a portion of a plan selected by the user.

3. The method according to claim 2, wherein the selected portion corresponds to a portion of the plan liked by the user for at least one of the series of actions.

4. The method according to claim 1, wherein the user feedback is stored for use in generating subsequent plans.

5. The method according to claim 1, wherein the user feedback records are indexed by a function of a list of facts that describe a situation.

6. The method according to claim 5, wherein the index further includes an incorporated list of subgoals.

7. The method according to claim 5, wherein the records include a list of weights for parameters of an evaluation function for rating actions.

8. The method according to claim 1, wherein the revised plan is generated by using weights associated with a state of the plan that matches a user feedback record.

9. A method, comprising:

generating first and second plans;

outputting the first and second plans to enable a user to perceive the first and second plans;

processing user feedback on the first and second plans; and

combining the first and second plans to provide a revised plan based upon the user feedback.

10. The method according to claim 9, further including dynamically altering weights of an evaluation function to incorporate the user feedback in the revised plan.

11. The method according to claim 10, further including generating the first plan by tasking a planner with a set of weights for an evaluation function and problem specification files.

12. The method according to claim 9, wherein the weights are multipliers in a linear combination of factors used by the evaluation function when rating an action for incorporation into the revised plan.

13. The method according to claim 9, wherein the first and second plans are generated by using first and second weightings that are different.

14. The method according to claim 13, wherein the first weightings are obtained from a user history file.

15. The method according to claim 13, wherein the first weightings are created randomly.

16. An article, comprising:

a storage medium having stored thereon instructions that when executed by a machine result in the following;

generating a first plan having a series of actions;

outputting the first plan to enable a user to perceive the plan;

receiving feedback from the user on the first plan;

generating a revised plan based upon the first plan and the feedback from the user.

17. The article according to claim 16, wherein the user feedback includes a portion of a first plan selected by the user.

18. The article according to claim 16, wherein the actions have associated records indexed by a function of a list of facts that describe a situation and the subgoals that have not been achieved in the situation.

19. The article according to claim 18, further including instructions for generating a second plan,

processing user feedback on the first and second plans;

and

combining the first and second plans to provide a revised plan based upon the user feedback.

20. The article according to claim 16, further including instructions for dynamically altering weights of an evaluation function to incorporate the user feedback in the revised plan.
