Check News in One Click: NLP-Empowered Pro-Kremlin Propaganda Detection

no code implementations28 Jan 2024 Veronika Solopova, Viktoriia Herman, Christoph Benzmüller, Tim Landgraf

Many European citizens become targets of the Kremlin propaganda campaigns, aiming to minimise public support for Ukraine, foster a climate of mistrust and disunity, and shape elections (Meister, 2022).

Propaganda detection

Automated multilingual detection of Pro-Kremlin propaganda in newspapers and Telegram posts

1 code implementation25 Jan 2023 Veronika Solopova, Oana-Iuliana Popescu, Christoph Benzmüller, Tim Landgraf

The full-scale conflict between the Russian Federation and Ukraine generated an unprecedented amount of news articles and social media data reflecting opposing ideologies and narratives.

A Rigorous Study Of The Deep Taylor Decomposition

1 code implementation14 Nov 2022 Leon Sixt, Tim Landgraf

Here, we investigate the DTD theory to better understand this perplexing behavior and found that the Deep Taylor Decomposition is equivalent to the basic gradient$\times$input method when the Taylor root points (an important parameter of the algorithm chosen by the user) are locally constant.

DNNR: Differential Nearest Neighbors Regression

no code implementations17 May 2022 Youssef Nader, Leon Sixt, Tim Landgraf

K-nearest neighbors (KNN) is one of the earliest and most established algorithms in machine learning.

Individuality in the hive - Learning to embed lifetime social behaviour of honey bees

no code implementations1 Jan 2021 Benjamin Wild, David Dormagen, Michael L Smith, Tim Landgraf

Honey bees are a popular model for complex social systems, in which global behavior emerges from the actions and interactions of thousands of individuals.

Interpretability Through Invertibility: A Deep Convolutional Network With Ideal Counterfactuals And Isosurfaces

no code implementations1 Jan 2021 Leon Sixt, Martin Schuessler, Philipp Weiß, Tim Landgraf

Using PCA on the classifier’s input, we can also create “isofactuals”– image interpolations with the same outcome but visually meaningful different features.

Restricting the Flow: Information Bottlenecks for Attribution

4 code implementations ICLR 2020 Karl Schulz, Leon Sixt, Federico Tombari, Tim Landgraf

Attribution methods provide insights into the decision-making of machine learning models like artificial neural networks.

When Explanations Lie: Why Many Modified BP Attributions Fail

1 code implementation ICML 2020 Leon Sixt, Maximilian Granz, Tim Landgraf

The paper provides a framework to assess the faithfulness of new and existing modified BP methods theoretically and empirically.

BioTracker: An Open-Source Computer Vision Framework for Visual Animal Tracking

no code implementations21 Mar 2018 Hauke Jürgen Mönck, Andreas Jörg, Tobias von Falkenhausen, Julian Tanke, Benjamin Wild, David Dormagen, Jonas Piotrowski, Claudia Winklmayr, David Bierbach, Tim Landgraf

Here we introduce BioTracker, an open-source computer vision framework, that provides programmers with core functionalities that are essential parts of a tracking software, such as video I/O, graphics overlays and mouse and keyboard interfaces.

Automatic localization and decoding of honeybee markers using deep convolutional neural networks

no code implementations13 Feb 2018 Benjamin Wild, Leon Sixt, Tim Landgraf

Tracking and identifying all bees in the colony over their lifetimes therefore may likely shed light on the interplay of individual differences and colony behavior.

Tracking all members of a honey bee colony over their lifetime

1 code implementation9 Feb 2018 Franziska Boenisch, Benjamin Rosemann, Benjamin Wild, Fernando Wario, David Dormagen, Tim Landgraf

Computational approaches to the analysis of collective behavior in social insects increasingly rely on motion paths as an intermediate data layer from which one can infer individual behaviors or social interactions.

Automatic detection and decoding of honey bee waggle dances

no code implementations22 Aug 2017 Fernando Wario, Benjamin Wild, Raúl Rojas, Tim Landgraf

In this paper, we describe our recording setup, the image processing steps performed for dance detection and decoding and an algorithm to map dances to the field.

RenderGAN: Generating Realistic Labeled Data

1 code implementation4 Nov 2016 Leon Sixt, Benjamin Wild, Tim Landgraf

Deep Convolutional Neuronal Networks (DCNNs) are showing remarkable performance on many computer vision tasks.
