Discrete Subgraph Sampling for Interpretable Graph based Visual Question Answering

COLING 2025main

Explainable artificial intelligence (XAI) aims to make machine learning models more transparent. While many approaches focus on generating explanations post-hoc, interpretable approaches, which generate the explanations intrinsically alongside the predictions, are relatively rare. In this work, we i…

Intrinsic Subgraph Generation for Interpretable Graph Based Visual Question Answering

COLING 2024main

The large success of deep learning based methods in Visual Question Answering (VQA) has concurrently increased the demand for explainable methods. Most methods in Explainable Artificial Intelligence (XAI) focus on generating post-hoc explanations rather than taking an intrinsic approach, the latter…

Prosody Is Not Identity: A Speaker Anonymization Approach Using Prosody Cloning

ICASSP 2023accepted

Prosody is closely linked to the identity of a speaker, leading to individual pitch and intonation patterns. Therefore, it is challenging in speaker anonymization to generate speech utterances that both keep the original audio’s main prosodic structure and preserve the speaker’s privacy. In this pap…

Beyond Accuracy: A Consolidated Tool for Visual Question Answering Benchmarking

EMNLP 2021system demonstrations

On the way towards general Visual Question Answering (VQA) systems that are able to answer arbitrary questions, the need arises for evaluation beyond single-metric leaderboards for specific datasets. To this end, we propose a browser-based benchmarking tool for researchers and challenge organizers,…
