Changes in Policy Preferences in German Tweets during the COVID Pandemic

no code implementations31 Jul 2023 Felix Biessmann

Quantifying political preferences in online social media remains challenging: The vast amount of content requires scalable automated extraction of political preferences -- however fine grained political preference extraction is difficult with current machine learning (ML) technology, due to the lack of data sets.

Automated Extraction of Fine-Grained Standardized Product Information from Unstructured Multilingual Web Data

no code implementations23 Feb 2023 Alexander Flick, Sebastian Jäger, Ivana Trajanovska, Felix Biessmann

Extracting structured information from unstructured data is one of the key challenges in modern information retrieval applications, including e-commerce.

GreenDB -- A Dataset and Benchmark for Extraction of Sustainability Information of Consumer Goods

1 code implementation21 Jul 2022 Sebastian Jäger, Alexander Flick, Jessica Adriana Sanchez Garcia, Kaspar von den Driesch, Karl Brendel, Felix Biessmann

We present initial results demonstrating that ML models trained with our data can reliably (F1 score 96%) predict the sustainability label of products.

CycleSense: Detecting Near Miss Incidents in Bicycle Traffic from Mobile Motion Sensors

no code implementations21 Apr 2022 Ahmet-Serdar Karakaya, Thomas Ritter, Felix Biessmann, David Bermbach

In cities worldwide, cars cause health and traffic problems whichcould be partly mitigated through an increased modal share of bicycles.

More Than Words: Towards Better Quality Interpretations of Text Classifiers

no code implementations23 Dec 2021 Muhammad Bilal Zafar, Philipp Schmidt, Michele Donini, Cédric Archambeau, Felix Biessmann, Sanjiv Ranjan Das, Krishnaram Kenthapadi

The large size and complex decision mechanisms of state-of-the-art text classifiers make it difficult for humans to understand their predictions, leading to a potential lack of trust by the users.

Quality Metrics for Transparent Machine Learning With and Without Humans In the Loop Are Not Correlated

no code implementations1 Jul 2021 Felix Biessmann, Dionysius Refiano

Interestingly the quality metrics computed without humans in the loop did not provide a consistent ranking of interpretability methods nor were they representative for how useful an explanation was for humans.

A Turing Test for Transparency

no code implementations21 Jun 2021 Felix Biessmann, Viktor Treu

This effect challenges the very goal of XAI and implies that responsible usage of transparent AI methods has to consider the ability of humans to distinguish machine generated from human explanations.

A psychophysics approach for quantitative comparison of interpretable computer vision models

no code implementations24 Nov 2019 Felix Biessmann, Dionysius Irza Refiano

While there are clear advantages of evaluations with no humans in the loop, such as scalability, reproducibility and less algorithmic bias than with humans in the loop, these metrics are limited in their usefulness if we do not understand how they relate to other metrics that take human cognition into account.

Quantifying Interpretability and Trust in Machine Learning Systems

1 code implementation20 Jan 2019 Philipp Schmidt, Felix Biessmann

Our results complement existing qualitative work on trust and interpretability by quantifiable measures that can serve as objectives for further improving methods in this field of research.

Automating Political Bias Prediction

no code implementations7 Aug 2016 Felix Biessmann

Standard text features extracted from speeches and manifestos of political parties are used to predict political bias in terms of political party affiliation and in terms of political views.

Effects of Stimulus Type and of Error-Correcting Code Design on BCI Speller Performance

no code implementations NeurIPS 2008 Jeremy Hill, Jason Farquhar, Suzanna Martens, Felix Biessmann, Bernhard Schölkopf

From an information-theoretic perspective, a noisy transmission system such as a visual Brain-Computer Interface (BCI) speller could benefit from the use of error-correcting codes.
