Computer Vision for Primate Behavior Analysis in the Wild

no code implementations29 Jan 2024 Richard Vogg, Timo Lüddecke, Jonathan Henrich, Sharmita Dey, Matthias Nuske, Valentin Hassler, Derek Murphy, Julia Fischer, Julia Ostner, Oliver Schülke, Peter M. Kappeler, Claudia Fichtel, Alexander Gail, Stefan Treue, Hansjörg Scherberger, Florentin Wörgötter, Alexander S. Ecker

With this perspective paper, we want to contribute towards closing this gap, by guiding behavioral scientists in what can be expected from current methods and steering computer vision researchers towards problems that are relevant to advance research in animal behavior.

Multi Sentence Description of Complex Manipulation Action Videos

no code implementations13 Nov 2023 Fatemeh Ziaeetabar, Reza Safabakhsh, Saeedeh Momtazi, Minija Tamosiunaite, Florentin Wörgötter

Automatic video description requires the generation of natural language statements about the actions, events, and objects in the video.

A Hierarchical Graph-based Approach for Recognition and Description Generation of Bimanual Actions in Videos

no code implementations1 Oct 2023 Fatemeh Ziaeetabar, Reza Safabakhsh, Saeedeh Momtazi, Minija Tamosiunaite, Florentin Wörgötter

To achieve this, we encode, first, the spatio-temporal inter dependencies between objects and actions with scene graphs and we combine this, in a second step, with a novel 3-level architecture creating a hierarchical attention mechanism using Graph Attention Networks (GATs).

Infant movement classification through pressure distribution analysis

no code implementations26 Jul 2022 Tomas Kulvicius, Dajie Zhang, Karin Nielsen-Saines, Sven Bölte, Marc Kraft, Christa Einspieler, Luise Poustka, Florentin Wörgötter, Peter B Marschik

Aiming at objective early detection of neuromotor disorders such as cerebral palsy, we proposed an innovative non-intrusive approach using a pressure sensing device to classify infant general movements (GMs).

3D object reconstruction and 6D-pose estimation from 2D shape for robotic grasping of objects

no code implementations2 Mar 2022 Marcell Wolnitza, Osman Kaya, Tomas Kulvicius, Florentin Wörgötter, Babette Dellen

We propose a method for 3D object reconstruction and 6D-pose estimation from 2D images that uses knowledge about object shape as the primary key.

Combining Optimal Path Search With Task-Dependent Learning in a Neural Network

no code implementations26 Jan 2022 Tomas Kulvicius, Minija Tamosiunaite, Florentin Wörgötter

The neural network has the same algorithmic complexity as Bellman-Ford and, in addition, we can show that network learning mechanisms (such as Hebbian learning) can adapt the weights in the network augmenting the resulting paths according to some task at hand.

Bootstrapping Concept Formation in Small Neural Networks

no code implementations26 Oct 2021 Minija Tamosiunaite, Tomas Kulvicius, Florentin Wörgötter

We argue that, first, Concepts are formed as closed representations, which are then consolidated by relating them to each other.

Human and Machine Action Prediction Independent of Object Information

no code implementations22 Apr 2020 Fatemeh Ziaeetabar, Jennifer Pomp, Stefan Pfeiffer, Nadiya El-Sourani, Ricarda I. Schubotz, Minija Tamosiunaite, Florentin Wörgötter

In spite of these constraints, our results show the subjects were able to predict actions in, on average, less than 64% of the action's duration.

One-shot path planning for multi-agent systems using fully convolutional neural network

no code implementations1 Apr 2020 Tomas Kulvicius, Sebastian Herzog, Timo Lüddecke, Minija Tamosiunaite, Florentin Wörgötter

In contrast to that, we propose a novel method by utilising fully convolutional neural network, which allows generation of complete paths, even for more than one agent, in one-shot, i. e., with a single prediction step.

Attention on Abstract Visual Reasoning

no code implementations14 Nov 2019 Lukas Hahne, Timo Lüddecke, Florentin Wörgötter, David Kappel

Our proposed hybrid model, represents an alternative on learning abstract relations using self-attention and demonstrates that the Transformer network is also well suited for abstract visual reasoning.

Action Prediction in Humans and Robots

no code implementations3 Jul 2019 Florentin Wörgötter, Fatemeh Ziaeetabar, Stefan Pfeiffer, Osman Kaya, Tomas Kulvicius, Minija Tamosiunaite

To achieve prediction, actions can be encoded by a series of events, where every event corresponds to a change in a (static or dynamic) relation between some of the objects in a scene.

Symbol Emergence in Cognitive Developmental Systems: a Survey

no code implementations26 Jan 2018 Tadahiro Taniguchi, Emre Ugur, Matej Hoffmann, Lorenzo Jamone, Takayuki Nagai, Benjamin Rosman, Toshihiko Matsuka, Naoto Iwahashi, Erhan Oztop, Justus Piater, Florentin Wörgötter

However, the symbol grounding problem was originally posed to connect symbolic AI and sensorimotor information and did not consider many interdisciplinary phenomena in human communication and dynamic symbol systems in our society, which semiotics considered.

Learning to Label Affordances from Simulated and Real Data

no code implementations26 Sep 2017 Timo Lüddecke, Florentin Wörgötter

An autonomous robot should be able to evaluate the affordances that are offered by a given situation.

Transfer entropy-based feedback improves performance in artificial neural networks

no code implementations13 Jun 2017 Sebastian Herzog, Christian Tetzlaff, Florentin Wörgötter

The structure of the majority of modern deep neural networks is characterized by uni- directional feed-forward connectivity across a very large number of layers.

Distributed Recurrent Neural Forward Models with Synaptic Adaptation for Complex Behaviors of Walking Robots

no code implementations11 Jun 2015 Sakyasingha Dasgupta, Dennis Goldschmidt, Florentin Wörgötter, Poramate Manoonpong

The locomotive behaviors can consist of a variety of walking patterns along with adaptation that allow the animals to deal with changes in environmental conditions, like uneven terrains, gaps, obstacles etc.
