DIVA: Dataset Derivative of a Learning Task

no code implementations ICLR 2022 Yonatan Dukler, Alessandro Achille, Giovanni Paolini, Avinash Ravichandran, Marzia Polito, Stefano Soatto

A learning task is a function from a training set to the validation error, which can be represented by a trained deep neural network (DNN).

Representation Consolidation from Multiple Expert Teachers

no code implementations29 Sep 2021 Zhizhong Li, Avinash Ravichandran, Charless Fowlkes, Marzia Polito, Rahul Bhotika, Stefano Soatto

Indeed, we observe experimentally that standard distillation of task-specific teachers, or using these teacher representations directly, **reduces** downstream transferability compared to a task-agnostic generalist model.

Representation Consolidation for Training Expert Students

no code implementations16 Jul 2021 Zhizhong Li, Avinash Ravichandran, Charless Fowlkes, Marzia Polito, Rahul Bhotika, Stefano Soatto

Traditionally, distillation has been used to train a student model to emulate the input/output functionality of a teacher.

Supervised Momentum Contrastive Learning for Few-Shot Classification

no code implementations26 Jan 2021 Orchid Majumder, Avinash Ravichandran, Subhransu Maji, Alessandro Achille, Marzia Polito, Stefano Soatto

In this work we investigate the complementary roles of these two sources of information by combining instance-discriminative contrastive learning and supervised learning in a single framework called Supervised Momentum Contrastive learning (SUPMOCO).

Mixed-Privacy Forgetting in Deep Networks

no code implementations CVPR 2021 Aditya Golatkar, Alessandro Achille, Avinash Ravichandran, Marzia Polito, Stefano Soatto

We show that the influence of a subset of the training samples can be removed -- or "forgotten" -- from the weights of a network trained on large-scale image classification tasks, and we provide strong computable bounds on the amount of remaining information after forgetting.

LQF: Linear Quadratic Fine-Tuning

no code implementations CVPR 2021 Alessandro Achille, Aditya Golatkar, Avinash Ravichandran, Marzia Polito, Stefano Soatto

Classifiers that are linear in their parameters, and trained by optimizing a convex loss function, have predictable behavior with respect to changes in the training data, initial conditions, and optimization.
