Chemnitz Symposium on Cognitive Systems
Thursday, 13 September 2018
Technische Universität Chemnitz
Altes Heizhaus, Straße der Nationen 62, 09111 Chemnitz
This symposium will focus on interdisciplinary research related to cognitive systems (artificial or biological). In particular, we
are interested in understanding how cognitive systems can detect helplessness in human subjects.
- Eight talks will show current research on these topics and promote discussion in the audience.
- Audience members are also invited to present their work in poster format.
- This symposium is free and aimed at researchers and students interested in Cognitive systems.

|10:05–10:50||Modeling the functional organization of themedial and ventral prefrontal cortex
Prof. Dr. Frédéric Alexandre, Inria Research Centre Bordeaux Sud-Ouest, France
The orbitofrontal cortex and anterior cingulate cortex are classically described for the selection of goals and actions, respectively. Experiments in neuroscience report a more complex and subtle situation that leads modelers to design more precise models and to wonder which numerical framework is best suited for this work. I report our analysis in this domain.
|11:00–11:20||Modeling the cortico-basal ganglio interaction for category learning
Francesc Villagrasa, Technische Universität Chemnitz, Germany
Physiological evidence show that both the basal ganglia (BG) and the prefrontal cortex (PFC) are involved in the acquisition of category representations. A theory suggests that the BG teach the PFC to slowly acquire category representations. Via a neuro-computational model inspired in this hypothesis, we replicate previous physiological and behavioral results and we show how the slow learning in the PFC push the categorization performance to higher levels than the ones achieved by the BG alone (fast learner). Furthermore, some of our model predictions have been reproduced and thus confirmed by experimental data.
|11:20–11:40||Hierarchical representations of actions in multiple basal ganglia loops

|13:30–13:50||Advanced Algorithms for Memory Hidden Markov Models|
Kim Schmidt, Technische Universität Chemnitz, Germany
For some applications of Hidden Markov Models (HMM) a-priori knowledge about the structure of the model parameters is available. We might know that some entries in these matrices are the same and others are zero. For training such a model, we could use the common Baum Welch Algorithm (BWA) to enforce the given structure after training or modify BWA to enforce it during training. These approaches lead to different results for the final trained HMM.
