Advanced sleep spindle identification with neural networks
Lars Kaulen, Justus T. C. Schwabedal, Jules Schneider +2
Sleep spindles are neurophysiological phenomena that appear to be linked to memory formation and other functions of the central nervous system, and that can be observed in electroe…
Automated scoring of pre-REM sleep in mice with deep learning
Niklas Grieger, Justus T. C. Schwabedal, Stefanie Wendel +2
Reliable automation of the labor-intensive manual task of scoring animal sleep can facilitate the analysis of long-term sleep studies. In recent years, deep-learning-based systems,…
Differentially Private Generation of Small Images
Justus T. C. Schwabedal, Pascal Michel, Mario S. Riontino
We explore the training of generative adversarial networks with differential privacy to anonymize image data sets. On MNIST, we numerically measure the privacy-utility trade-off us…
Automated Classification of Sleep Stages and EEG Artifacts in Mice with Deep Learning
Justus T. C. Schwabedal, Daniel Sippel, Moritz D. Brandt +1
Sleep scoring is a necessary and time-consuming task in sleep studies. In animal models (such as mice) or in humans, automating this tedious process promises to facilitate long-ter…
Addressing Class Imbalance in Classification Problems of Noisy Signals by using Fourier Transform Surrogates
Justus T. C. Schwabedal, John C. Snyder, Ayse Cakmak +2
Randomizing the Fourier-transform (FT) phases of temporal-spatial data generates surrogates that approximate examples from the data-generating distribution. We propose such FT surr…
Qualitative and Quantitative Stability Analysis of Penta-rhythmic Circuits
Justus T. C. Schwabedal, Drake E. Knapper, A. L. Shilnikov
Inhibitory circuits of relaxation oscillators are often-used models for the dynamics of biological networks. We present a qualitative and quantitative stability analysis of such a…
Key bifurcations of bursting polyrhythms in 3-cell central pattern generators
Jeremy Wojcik, Robert Clewley, Justus Schwabedal +1
We identify and describe the key qualitative rhythmic states in various 3-cell network motifs of a multifunctional central pattern generator (CPG). Such CPGs are neural microcircui…
Phase Description of Stochastic Oscillations
Justus T. C. Schwabedal, Arkady Pikovsky
We introduce an invariant phase description of stochastic oscillations by generalizing the concept of standard isophases. The average isophases are constructed as sections in the s…
Optimal Phase Description of Chaotic Oscillators
Justus T. C. Schwabedal, Arkady Pikovsky, Björn Kralemann +1
We introduce an optimal phase description of chaotic oscillations by generalizing the concept of isochrones. On chaotic attractors possessing a general phase description, we define…
Effective phase description of noise-perturbed and noise-induced oscillations
Justus T. C. Schwabedal, Arkady Pikovsky
An effective description of a general class of stochastic phase oscillators is presented. For this, the effective phase velocity is defined either by invariant probability density…
Effective phase dynamics of noise-induced oscillations in excitable systems
Justus T. C. Schwabedal, Arkady Pikovsky
We develop an effective description of noise-induced oscillations based on deterministic phase dynamics. The phase equation is constructed to exhibit correct frequency and distribu…
