Available observation time regulates optimal balance between sensitivity and confidence

no code implementations15 Jul 2023 Sahel Azizpour, Viola Priesemann, Johannes Zierenberg, Anna Levina

Tasks that require information about the world imply a trade-off between the time spent on observation and the variance of the response.

Infomorphic networks: Locally learning neural networks derived from partial information decomposition

no code implementations3 Jun 2023 Marcel Graetz, Abdullah Makkeh, Andreas C. Schneider, David A. Ehrlich, Viola Priesemann, Michael Wibral

Understanding the intricate cooperation among individual neurons in performing complex tasks remains a challenge to this date.

Model-based assessment of sampling protocols for infectious disease genomic surveillance

1 code implementation19 Jan 2023 Sebastian Contreras, Karen Y. Oróstica, Anamaria Daza-Sanchez, Joel Wagner, Philipp Dönges, David Medina-Ortiz, Matias Jara, Ricardo Verdugo, Carlos Conca, Viola Priesemann, Álvaro Olivera-Nappa

Consequently, it is convenient for countries with comparatively few resources to operate at lower sequencing rates, thereby profiting the most from adaptive sampling.

Impact of the Euro 2020 championship on the spread of COVID-19

2 code implementations18 Jan 2023 Jonas Dehning, Sebastian B. Mohr, Sebastian Contreras, Philipp Dönges, Emil N. Iftekhar, Oliver Schulz, Philip Bechtle, Viola Priesemann

Large-scale events like the UEFA Euro~2020 football (soccer) championship offer a unique opportunity to quantify the impact of gatherings on the spread of COVID-19, as the number and dates of matches played by participating countries resembles a randomized study.

SIR-Model for Households

no code implementations11 Jan 2023 Philipp Doenges, Thomas Götz, Tyll Krueger, Karol Niedzielewski, Viola Priesemann, Moritz Schaefer

In this setting, the basic reproduction number as well as prevalence and the peak of an infection wave in a population with given households size distribution can be computed analytically.

A Measure of the Complexity of Neural Representations based on Partial Information Decomposition

1 code implementation21 Sep 2022 David A. Ehrlich, Andreas C. Schneider, Viola Priesemann, Michael Wibral, Abdullah Makkeh

However, the specific way in which this mutual information about the classification label is distributed among the individual neurons is not well understood: While parts of it may only be obtainable from specific single neurons, other parts are carried redundantly or synergistically by multiple neurons.

Tackling the subsampling problem to infer collective properties from limited data

no code implementations12 Sep 2022 Anna Levina, Viola Priesemann, Johannes Zierenberg

However, despite the development of large-scale data-acquisition techniques, experimental observations are often limited to a tiny fraction of the system.

Modular architecture facilitates noise-driven control of synchrony in neuronal networks

no code implementations21 May 2022 Hideaki Yamamoto, F. Paul Spitzner, Taiki Takemuro, Victor Buendía, Carla Morante, Tomohiro Konno, Shigeo Sato, Ayumi Hirano-Iwata, Viola Priesemann, Miguel A. Muñoz, Johannes Zierenberg, Jordi Soriano

Brain functions require both segregated processing of information in specialized circuits, as well as integration across circuits to perform high-level information processing.

Dendritic predictive coding: A theory of cortical computation with spiking neurons

no code implementations11 May 2022 Fabian A. Mikulasch, Lucas Rudelt, Michael Wibral, Viola Priesemann

However, experimental evidence for error units, which are central to the theory, is inconclusive, and it remains unclear how hPC can be implemented with spiking neurons.

Information-theoretic analyses of neural data to minimize the effect of researchers' assumptions in predictive coding studies

no code implementations21 Mar 2022 Patricia Wollstadt, Daniel L. Rathbun, W. Martin Usrey and, André Moraes Bastos, Michael Lindner, Viola Priesemann, Michael Wibral

We demonstrate our approach by investigating two opposing accounts of predictive coding-like processing strategies, where we quantify the building blocks of predictive coding, namely predictability of inputs and transfer of information, by local active information storage and local transfer entropy.

Interplay between risk perception, behaviour, and COVID-19 spread

1 code implementation22 Dec 2021 Philipp Dönges, Joel Wagner, Sebastian Contreras, Emil Iftekhar, Simon Bauer, Sebastian B. Mohr, Jonas Dehning, André Calero Valdez, Mirjam Kretzschmar, Michael Mäs, Kai Nagel, Viola Priesemann

They are complemented by voluntary health-protective behaviour, building a complex interplay between risk perception, behaviour, and disease spread.

Local dendritic balance enables learning of efficient representations in networks of spiking neurons

no code implementations23 Oct 2020 Fabian Alexander Mikulasch, Lucas Rudelt, Viola Priesemann

How can neural networks learn to efficiently represent complex and high-dimensional inputs via local plasticity mechanisms?

Assessing criticality in pre-seizure single-neuron activity of human epileptic cortex

no code implementations22 Apr 2020 Annika Hagemann, Jens Wilting, Bita Samimizad, Florian Mormann, Viola Priesemann

Epileptic seizures are characterized by abnormal and excessive neural activity, where cortical network dynamics seem to become unstable.

Inferring COVID-19 spreading rates and potential change points for case number forecasts

8 code implementations2 Apr 2020 Jonas Dehning, Johannes Zierenberg, F. Paul Spitzner, Michael Wibral, Joao Pinheiro Neto, Michael Wilczek, Viola Priesemann

As COVID-19 is rapidly spreading across the globe, short-term modeling forecasts provide time-critical information for decisions on containment and mitigation strategies.

Bayesian Inference

Sampling effects and measurement overlap can bias the inference of neuronal avalanches

no code implementations22 Oct 2019 Joao Pinheiro Neto, Franz Paul Spitzner, Viola Priesemann

To date, it is still impossible to sample the entire mammalian brain with single-neuron precision.

Description of spreading dynamics by microscopic network models and macroscopic branching processes can differ due to coalescence

1 code implementation24 May 2019 Johannes Zierenberg, Jens Wilting, Viola Priesemann, Anna Levina

Spreading processes are conventionally monitored on a macroscopic level by counting the number of incidences over time.

Tailored ensembles of neural networks optimize sensitivity to stimulus statistics

1 code implementation24 May 2019 Johannes Zierenberg, Jens Wilting, Viola Priesemann, Anna Levina

The dynamic range of stimulus processing in living organisms is much larger than a single neural network can explain.
