Loss Balancing for Fair Supervised Learning

1 code implementation7 Nov 2023 Mohammad Mahdi Khalili, Xueru Zhang, Mahed Abroshan

Imposing EL on the learning process leads to a non-convex optimization problem even if the loss function is convex, and the existing fair learning algorithms cannot properly be adopted to find the fair predictor under the EL constraint.

Revisiting DeepFool: generalization and improvement

1 code implementation22 Mar 2023 Alireza Abdollahpourrostam, Mahed Abroshan, Seyed-Mohsen Moosavi-Dezfooli

Our proposed attacks are also suitable for evaluating the robustness of large models and can be used to perform adversarial training (AT) to achieve state-of-the-art robustness to minimal l2 adversarial perturbations.

An Information-theoretical Approach to Semi-supervised Learning under Covariate-shift

no code implementations24 Feb 2022 Gholamali Aminian, Mahed Abroshan, Mohammad Mahdi Khalili, Laura Toni, Miguel R. D. Rodrigues

A common assumption in semi-supervised learning is that the labeled, unlabeled, and test data are drawn from the same distribution.

Fair Sequential Selection Using Supervised Learning Models

1 code implementation NeurIPS 2021 Mohammad Mahdi Khalili, Xueru Zhang, Mahed Abroshan

This observation implies that the fairness notions used in classification problems are not suitable for a selection problem where the applicants compete for a limited number of positions.

Non-convex Optimization for Learning a Fair Predictor under Equalized Loss Fairness Constraint

no code implementations29 Sep 2021 Mohammad Mahdi Khalili, Xueru Zhang, Mahed Abroshan, Iman Vakilinia

In general, finding a fair predictor leads to a constrained optimization problem, and depending on the fairness notion, it may be non-convex.

Interpreting Black-boxes Using Primitive Parameterized Functions

no code implementations29 Sep 2021 Mahed Abroshan, Saumitra Mishra, Mohammad Mahdi Khalili

One approach for interpreting black-box machine learning models is to find a global approximation of the model using simple interpretable functions, which is called a metamodel (a model of the model).

Conservative Policy Construction Using Variational Autoencoders for Logged Data with Missing Values

no code implementations8 Sep 2021 Mahed Abroshan, Kai Hou Yip, Cem Tekin, Mihaela van der Schaar

Secondly, such datasets are usually imperfect, additionally cursed with missing values in the attributes of features.

Improving Fairness and Privacy in Selection Problems

no code implementations7 Dec 2020 Mohammad Mahdi Khalili, Xueru Zhang, Mahed Abroshan, Somayeh Sojoudi

In this work, we study the possibility of using a differentially private exponential mechanism as a post-processing step to improve both fairness and privacy of supervised learning models.
