Prospector Heads: Generalized Feature Attribution for Large Models & Data

1 code implementation18 Feb 2024 Gautam Machiraju, Alexander Derry, Arjun Desai, Neel Guha, Amir-Hossein Karimi, James Zou, Russ Altman, Christopher Ré, Parag Mallick

Feature attribution, the ability to localize regions of the input data that are relevant for classification, is an important capability for machine learning models in scientific and biomedical domains.

Causal Adversarial Perturbations for Individual Fairness and Robustness in Heterogeneous Data Spaces

no code implementations17 Aug 2023 Ahmad-Reza Ehyaei, Kiarash Mohammadi, Amir-Hossein Karimi, Samira Samadi, Golnoosh Farnadi

In this paper, we propose a novel approach that examines the relationship between individual fairness, adversarial robustness, and structural causal models in heterogeneous data spaces, particularly when dealing with discrete sensitive attributes.

Robustness Implies Fairness in Causal Algorithmic Recourse

2 code implementations7 Feb 2023 Ahmad-Reza Ehyaei, Amir-Hossein Karimi, Bernhard Schölkopf, Setareh Maghsudi

Algorithmic recourse aims to disclose the inner workings of the black-box decision process in situations where decisions have significant consequences, by providing recommendations to empower beneficiaries to achieve a more favorable outcome.

On the Adversarial Robustness of Causal Algorithmic Recourse

1 code implementation21 Dec 2021 Ricardo Dominguez-Olmedo, Amir-Hossein Karimi, Bernhard Schölkopf

Algorithmic recourse seeks to provide actionable recommendations for individuals to overcome unfavorable classification outcomes from automated decision-making systems.

Scaling Guarantees for Nearest Counterfactual Explanations

no code implementations10 Oct 2020 Kiarash Mohammadi, Amir-Hossein Karimi, Gilles Barthe, Isabel Valera

Counterfactual explanations (CFE) are being widely used to explain algorithmic decisions, especially in consequential decision-making contexts (e. g., loan approval or pretrial bail).

counterfactual Decision Making

A survey of algorithmic recourse: definitions, formulations, solutions, and prospects

no code implementations8 Oct 2020 Amir-Hossein Karimi, Gilles Barthe, Bernhard Schölkopf, Isabel Valera

Machine learning is increasingly used to inform decision-making in sensitive situations where decisions have consequential effects on individuals' lives.

Algorithmic recourse under imperfect causal knowledge: a probabilistic approach

1 code implementation NeurIPS 2020 Amir-Hossein Karimi, Julius von Kügelgen, Bernhard Schölkopf, Isabel Valera

Recent work has discussed the limitations of counterfactual explanations to recommend actions for algorithmic recourse, and argued for the need of taking causal relationships between features into consideration.

Algorithmic Recourse: from Counterfactual Explanations to Interventions

2 code implementations14 Feb 2020 Amir-Hossein Karimi, Bernhard Schölkopf, Isabel Valera

As machine learning is increasingly used to inform consequential decision-making (e. g., pre-trial bail and loan approval), it becomes important to explain how the system arrived at its decision, and also suggest actions to achieve a favorable decision.

Model-Agnostic Counterfactual Explanations for Consequential Decisions

1 code implementation27 May 2019 Amir-Hossein Karimi, Gilles Barthe, Borja Balle, Isabel Valera

Predictive models are being increasingly used to support consequential decision making at the individual level in contexts such as pretrial bail and loan approval.

Deep Variational Sufficient Dimensionality Reduction

no code implementations18 Dec 2018 Ershad Banijamali, Amir-Hossein Karimi, Ali Ghodsi

We consider the problem of sufficient dimensionality reduction (SDR), where the high-dimensional observation is transformed to a low-dimensional sub-space in which the information of the observations regarding the label variable is preserved.

SRP: Efficient class-aware embedding learning for large-scale data via supervised random projections

1 code implementation7 Nov 2018 Amir-Hossein Karimi, Alexander Wong, Ali Ghodsi

While stochastic approximation strategies have been explored for unsupervised dimensionality reduction to tackle this challenge, such approaches are not well-suited for accelerating computational speed for supervised dimensionality reduction.

JADE: Joint Autoencoders for Dis-Entanglement

no code implementations24 Nov 2017 Ershad Banijamali, Amir-Hossein Karimi, Alexander Wong, Ali Ghodsi

The problem of feature disentanglement has been explored in the literature, for the purpose of image and video processing and text analysis.
