Abstract
A computing system including one or more processing devices configured to receive a forgetting dataset including forgetting-target prompt-output pairs. The forgetting-target prompt-output pairs each include a forgetting-target prompt that has been input into a generative language model and a forgetting-target output generated at the generative language model. The processing devices are further configured to receive a remembering dataset including remembering-target prompt-output pairs that each include a remembering-target prompt that has been input into the generative language model and a remembering-target output generated at the generative language model. The processing devices are further configured to compute an unlearning loss term and a remembering loss term based at least in part on the forgetting dataset and the remembering dataset, respectively. The processing devices are further configured to perform unlearning updates at the generative language model by performing gradient descent with respect to a loss that includes the loss terms.
