Unlearning What You Have Learned

چکیده
When Bayesians set out to model rational constraints on the ways agents’ degrees of belief evolve over time, they usually start by stipulating that the agents they are modeling never forget information. But Frank Arntzenius has shown that there can be substantive constraints on the relation between an agent’s degrees of belief at two times even if the agent has forgotten some relevant information between those two times. Consider the following example, adapted from (Arntzenius 2003):

A Theoretical Overview of Unlearning in Engineering
Unlearning is the deliberate undoing or reversal of what has been previously learned. This skill has been acknowledged in business and academia as being increasingly important for engineers in a highly changeable 21st century environment; additionally, industry have recently flagged a real-world skill deficit in graduates that can be remedied using the concept of unlearning. This paper shows th...

of recognizing an important correlation if we obtained one. Nevertheless, I contend that much has been learned about cancer and cancer chemotherapy—at the molecular level, the cellular level, the animal tumor level, and the clinical level. We may even be approaching a point when objective interdigitation of what we have learned from many model systems can lead to more rational and efficient a...
متن کاملContext, ambiguity, and unlearning: sources of relapse after behavioral extinction.
There is now ample evidence that extinction, the loss of learned performance that occurs when a Pavlovian signal or an instrumental action is repeatedly presented without its reinforcer, does not reflect a destruction of the original learning. This article summarizes the evidence and extends and updates earlier reviews. The main alternative to "unlearning" is the idea that extinction (as well a...
متن کاملThe consolidation of learning during sleep: comparing the pseudorehearsal and unlearning accounts
We suggest that any brain-like (artificial neural network based) learning system will need a sleep-like mechanism for consolidating newly learned information if it wishes to cope with the sequential/ongoing learning of significantly new information. We summarise and explore two possible candidates for a computational account of this consolidation process in Hopfield type networks. The "pseudore...
