Changing One's Mind: Erase or Rewind?
Celia da Costa Pereira, Andrea G. B. Tettamanzi and Serena Villata
We address the issue, in cognitive agents, of possible loss of previous information, which later might turn out to be correct when new information becomes available. To this aim, we propose a framework for changing the agent's mind without erasing forever previous information, thus allowing its recovery in case the change turns out to be wrong.
