Towards Non-Adversarial Algorithmic Recourse

no code implementations15 Mar 2024 Tobias Leemann, Martin Pawelczyk, Bardh Prenkaj, Gjergji Kasneci

We subsequently investigate how different components in the objective functions, e. g., the machine learning model or cost function used to measure distance, determine whether the outcome can be considered an adversarial example or not.

Gaussian Membership Inference Privacy

1 code implementation NeurIPS 2023 Tobias Leemann, Martin Pawelczyk, Gjergji Kasneci

In particular, we derive a parametric family of $f$-MIP guarantees that we refer to as $\mu$-Gaussian Membership Inference Privacy ($\mu$-GMIP) by theoretically analyzing likelihood ratio-based membership inference attacks on stochastic gradient descent (SGD).

I Prefer not to Say: Protecting User Consent in Models with Optional Personal Data

1 code implementation25 Oct 2022 Tobias Leemann, Martin Pawelczyk, Christian Thomas Eberle, Gjergji Kasneci

In this work, we show that the decision not to share data can be considered as information in itself that should be protected to respect users' privacy.

On the Trade-Off between Actionable Explanations and the Right to be Forgotten

no code implementations30 Aug 2022 Martin Pawelczyk, Tobias Leemann, Asia Biega, Gjergji Kasneci

Thus, our work raises fundamental questions about the compatibility of "the right to an actionable explanation" in the context of the "right to be forgotten", while also providing constructive insights on the determining factors of recourse robustness.

When are Post-hoc Conceptual Explanations Identifiable?

1 code implementation28 Jun 2022 Tobias Leemann, Michael Kirchhof, Yao Rong, Enkelejda Kasneci, Gjergji Kasneci

Interest in understanding and factorizing learned embedding spaces through conceptual explanations is steadily growing.

A Consistent and Efficient Evaluation Strategy for Attribution Methods

1 code implementation1 Feb 2022 Yao Rong, Tobias Leemann, Vadim Borisov, Gjergji Kasneci, Enkelejda Kasneci

With a variety of local feature attribution methods being proposed in recent years, follow-up work suggested several evaluation strategies.

Distribution Preserving Multiple Hypotheses Prediction for Uncertainty Modeling

1 code implementation6 Oct 2021 Tobias Leemann, Moritz Sackmann, Jörn Thielecke, Ulrich Hofmann

Many supervised machine learning tasks, such as future state prediction in dynamical systems, require precise modeling of a forecast's uncertainty.

Deep Neural Networks and Tabular Data: A Survey

2 code implementations5 Oct 2021 Vadim Borisov, Tobias Leemann, Kathrin Seßler, Johannes Haug, Martin Pawelczyk, Gjergji Kasneci

Moreover, we discuss deep learning approaches for generating tabular data, and we also provide an overview over strategies for explaining deep models on tabular data.
