Inference-time Unlearning Using Conformal Prediction

Somnath Basu Roy Chowdhury, Rahul Kidambi, Avinava Dubey +4

Machine unlearning is the process of efficiently removing specific information from a trained machine learning model without retraining from scratch. Existing unlearning methods, w…

Fundamental Limits of Perfect Concept Erasure

Somnath Basu Roy Chowdhury, Avinava Dubey, Ahmad Beirami +4

Concept erasure is the task of erasing information about a concept (e.g., gender or race) from a representation set while retaining the maximum possible utility -- information from…

Towards Scalable Exact Machine Unlearning Using Parameter-Efficient Fine-Tuning

Somnath Basu Roy Chowdhury, Krzysztof Choromanski, Arijit Sehanobish +2

Machine unlearning is the process of efficiently removing the influence of a training data instance from a trained machine learning model without retraining it from scratch. A popu…

Fast Tree-Field Integrators: From Low Displacement Rank to Topological Transformers

Krzysztof Choromanski, Arijit Sehanobish, Somnath Basu Roy Chowdhury +4

We present a new class of fast polylog-linear algorithms based on the theory of structured matrices (in particular low displacement rank) for integrating tensor fields defined on w…
