Robust mixture learning when outliers overwhelm small groups
DD*, Rares-Darius Buhai*, Stefan Tiegel, Alexander Wolters, Gleb Novikov, Amartya Sanyal, David Steurer, Fanny Yang
NeurIPS, 2024

We propose an efficient meta-algorithm for recoving means of a mixture model in the presence of large additive contaminations.

On the growth of mistakes in differentially private online learning: a lower bound perspective
DD, Kristof Szabo, Amartya Sanyal
COLT, 2024
arxiv /
poster /
We prove that for a certain class of algorithms, the number of mistakes for online learning under differential privacy constraint must grow logarithmically.

Asymptotics of learning with deep structured (random) features
Dominik Schröder*, DD*, Hugo Cui*, Bruno Loureiro
ICML, 2024
arxiv /
poster /
We derive a deterministic equivalent for the generalization error of general Lipschitz functions.
Furthermore, we prove a linearization for a sample covariance matrix of a structured random feature model with two hidden layers.

We prove that the standard greedy algorithm is order-optimal for the hitting set problem in the random bernoulli case.
