Artificial Intelligence - The Frame Problem.


 John McCarthy and Patrick Hayes discovered the frame problem in 1969.

The problem concerns representing the effects of actions in logic-based artificial intelligence.

Formal logic is used to define facts about the world, such as a car can be started when the key is placed in the ignition and turned and that pressing the accelerator causes it to move forward.

However, the latter fact does not explicitly state that the car remains on after pressing the accelerator.

To correct this, the fact must be expanded to “pressing the accelerator moves the car forward and does not turn it off.” However, this fact must be augmented further to describe many other scenarios (e.g., that the driver also remains in the vehicle) (e.g., that the driver also remains in the vehicle).

The frame problem highlights an issue in logic involving the construction of facts that do not require enumerating thousands of trivial effects.

After its discovery by artificial intelligence researchers, the frame issue was taken up by philosophers.

Their version of the issue could be appropriately dubbed the world update problem since it involves updating frames of reference.

For example, how do you know your dog (or other pet) is where you last saw them without seeing them again? In a philosophic perspective, the frame issue is concerned with how well a person's perception of their environment corresponds to reality and when that understanding should be changed.

As intelligent agents plan activities in more complicated environments, they will have to deal with this issue.

To solve the logic version of the frame problem, a number of solutions have been proposed.

The philosophical problem, on the other hand, remains unsolved.

Both must be solved in order for artificial intelligence to behave intelligently.
