Recommendation Fairness in Social Networks Over Time

no code implementations5 Feb 2024 Meng Cao, Hussain Hussain, Sandipan Sikdar, Denis Helic, Markus Strohmaier, Roman Kern

We further study how interventions on network properties influence fairness by examining counterfactual scenarios with alternative evolution outcomes and differing network properties.

A Review of the Role of Causality in Developing Trustworthy AI Systems

1 code implementation14 Feb 2023 Niloy Ganguly, Dren Fazlija, Maryam Badar, Marco Fisichella, Sandipan Sikdar, Johanna Schrader, Jonas Wallat, Koustav Rudra, Manolis Koubarakis, Gourab K. Patro, Wadhah Zai El Amri, Wolfgang Nejdl

This review aims to provide the reader with an overview of causal methods that have been developed to improve the trustworthiness of AI models.

SensePOLAR: Word sense aware interpretability for pre-trained contextual word embeddings

1 code implementation11 Jan 2023 Jan Engler, Sandipan Sikdar, Marlene Lutz, Markus Strohmaier

To address this limitation, we present SensePOLAR, an extension of the original POLAR framework that enables word-sense aware interpretability for pre-trained contextual word embeddings.

Properties of Group Fairness Metrics for Rankings

no code implementations29 Dec 2022 Tobias Schumacher, Marlene Lutz, Sandipan Sikdar, Markus Strohmaier

By virtue of their diverse application contexts, we argue that such a comparative analysis is not straightforward.

Adversarial Inter-Group Link Injection Degrades the Fairness of Graph Neural Networks

1 code implementation13 Sep 2022 Hussain Hussain, Meng Cao, Sandipan Sikdar, Denis Helic, Elisabeth Lex, Markus Strohmaier, Roman Kern

We hope our findings raise awareness about this issue in our community and lay a foundation for the future development of GNN models that are more robust to such attacks.

Integrated Directional Gradients: Feature Interaction Attribution for Neural NLP Models

1 code implementation ACL 2021 Sandipan Sikdar, Parantapa Bhattacharya, Kieran Heese

In contrast, our formulation is inspired by axioms satisfied by characteristic functions as well as solution concepts in cooperative game theory literature.

The POLAR Framework: Polar Opposites Enable Interpretability of Pre-Trained Word Embeddings

1 code implementation27 Jan 2020 Binny Mathew, Sandipan Sikdar, Florian Lemmerich, Markus Strohmaier

We introduce POLAR - a framework that adds interpretability to pre-trained word embeddings via the adoption of semantic differentials.

StRE: Self Attentive Edit Quality Prediction in Wikipedia

1 code implementation ACL 2019 Soumya Sarkar, Bhanu Prakash Reddy, Sandipan Sikdar, Animesh Mukherjee

Wikipedia can easily be justified as a behemoth, considering the sheer volume of content that is added or removed every minute to its several projects.
