Transcript of What makes social interactions hard?
1941: The Allies knew the code. The Nazis didn't know that the Allies knew the code.
1945: The Allies knew the code. The Nazis knew that the Allies knew the code. The Allies didn't know that the Nazis knew that the Allies knew the code. Reasoning about knowledge Reasoning about knowledge can be hard. Still, we do that every day and we are pretty good at it. As yet, computers cannot 'read minds'. LL LR RL RR Why is it hard to simulate reasoning about knowledge? Global (logical) perspective lists all possibilities. Too complex representations The goal of the project To propose simpler representations and prove that they make reasoning about knowledge easier Epistemic horizon Agent's internal perspective Right, Left Relate to the models of human cognition To sum up Simpler logical representations
Factors contributing to the complexity
