Language Generation with Replay: A Learning-Theoretic View of Model Collapse

Giorgio Racca, Michal Valko, Amartya Sanyal

As scaling laws push the training of frontier large language models (LLMs) toward ever-growing data requirements, training pipelines are approaching a regime where much of the publ…

Less Noise, Same Certificate: Retain Sensitivity for Unlearning

Carolin Heinzler, Kasra Malihi, Amartya Sanyal

Certified machine unlearning aims to provably remove the influence of a deletion set from a model trained on a dataset , by producing an unlearned output that is statistical…

Fairness for the People, by the People: Minority Collective Action

Omri Ben-Dov, Samira Samadi, Amartya Sanyal +1

Machine learning models often preserve biases present in training data, leading to unfair treatment of certain minority groups. Despite an array of existing firm-side bias mitigati…

Provable unlearning in topic modeling and downstream tasks

Stanley Wei, Sadhika Malladi, Sanjeev Arora +1

Machine unlearning algorithms are increasingly important as legal concerns arise around the provenance of training data, but verifying the success of unlearning is often difficult.…
