DART: A Principled Approach to Adversarially Robust Unsupervised Domain Adaptation

no code implementations16 Feb 2024 Yunjuan Wang, Hussein Hazimeh, Natalia Ponomareva, Alexey Kurakin, Ibrahim Hammoud, Raman Arora

To address this challenge, we first establish a generalization bound for the adversarial target loss, which consists of (i) terms related to the loss on the data, and (ii) a measure of worst-case domain divergence.

Leveraging Importance Weights in Subset Selection

no code implementations28 Jan 2023 Gui Citovsky, Giulia Desalvo, Sanjiv Kumar, Srikumar Ramalingam, Afshin Rostamizadeh, Yunjuan Wang

In such a setting, an algorithm can sample examples one at a time but, in order to limit overhead costs, is only able to update its state (i. e. further train model weights) once a large enough batch of examples is selected.

Adversarial Robustness is at Odds with Lazy Training

no code implementations18 Jun 2022 Yunjuan Wang, Enayat Ullah, Poorya Mianjy, Raman Arora

Recent works show that adversarial examples exist for random neural networks [Daniely and Schacham, 2020] and that these examples can be found using a single step of gradient ascent [Bubeck et al., 2021].

OWA aggregation of multi-criteria with mixed uncertain fuzzy satisfactions

no code implementations24 Jan 2019 Yunjuan Wang, Yong Deng

We apply the Ordered Weighted Averaging (OWA) operator in multi-criteria decision-making.
