Statistically Optimal Generative Modeling with Maximum Deviation from the Empirical Distribution

ICML 2024poster

This paper explores the problem of generative modeling, aiming to simulate diverse examples from an unknown distribution based on observed examples. While recent studies have focused on quantifying the statistical precision of popular algorithms, there is a lack of mathematical evaluation regarding…

Matching Map Recovery with an Unknown Number of Outliers

AISTATS 2023poster

We consider the problem of finding the matching map between two sets of $d$-dimensional noisy feature-vectors. The distinctive feature of our setting is that we do not assume that all the vectors of the first set have their corresponding vector in the second set. If $n$ and $m$ are the sizes of thes…

Failure Modes of Domain Generalization Algorithms

CVPR 2022oral

Domain generalization algorithms use training data from multiple domains to learn models that generalize well to unseen domains. While recently proposed benchmarks demonstrate that most of the existing algorithms do not outperform simple baselines, the established evaluation methods fail to expose t…
