Is your algorithm unlearning or untraining?

Eleni Triantafillou, Ahmed Imtiaz Humayun, Monica Ribero +3

As models are getting larger and are trained on increasing amounts of data, there has been an explosion of interest into how we can ``delete'' specific data points or behaviours fr…

Step-resolved data attribution for looped transformers

Georgios Kaissis, David Mildenberger, Juan Felipe Gomez +2

We study how individual training examples shape the internal computation of looped transformers, where a shared block is applied for recurrent iterations to enable latent reas…

Redirection for Erasing Memory (REM): Towards a universal unlearning method for corrupted data

Stefan Schoepf, Michael Curtis Mozer, Nicole Elyse Mitchell +4

Machine unlearning is studied for a multitude of tasks, but specialization of unlearning methods to particular tasks has made their systematic comparison challenging. To address th…

Your Privacy Depends on Others: Collusion Vulnerabilities in Individual Differential Privacy

Johannes Kaiser, Alexander Ziller, Eleni Triantafillou +2

Individual Differential Privacy (iDP) promises users control over their privacy, but this promise can be broken in practice. We reveal a previously overlooked vulnerability in samp…

Counterfactual Influence as a Distributional Quantity

Matthieu Meeus, Igor Shilov, Georgios Kaissis +1

Machine learning models are known to memorize samples from their training data, raising concerns around privacy and generalization. Counterfactual self-influence is a popular metri…
