Model-free quantification of time-series predictability

Joshua Garland, Ryan James, Elizabeth Bradley
2014 Physical Review E  
We conjecture that the inherent complexity of real-world time-series data---which results from the dimension, nonlinearity, and non-stationarity of the generating process, as well as from measurement issues  ...  For each time series, we construct predictions using a wide variety of forecast models, then compare the accuracy of the predictions with the permutation entropy of that time series.  ...  Here, the random-walk predictor is the best of the methods used here.  ...

Complex networks: Structure and dynamics

S BOCCALETTI, V LATORA, Y MORENO, M CHAVEZ, D HWANG
2006 Physics reports  
The massive and comparative analysis of networks from different fields has produced a series of unexpected and dramatic results. The first issue that has been faced is certainly structural.  ...  , with the main focus moving from the analysis of small networks to that of systems with thousands or millions of nodes, and with a renewed attention to the properties of networks of dynamical units.  ...  Their sharing of very stimulating and fruitful discussions (or unpublished results on the subjects treated in this report) is largely responsible for our effort to provide a new account of this rapidly  ...

30th Annual Computational Neuroscience Meeting: CNS*2021–Meeting Abstracts

2021 Journal of Computational Neuroscience  
Currently, most functional models of neural activity are based on firing rates, while the most relevant signals for inter-neuron communication are spikes.  ...  One of the goals of neuroscience is to understand the computational principles that describe the formation of behaviorally relevant signals in the brain, as well as how these computations are realized  ...  Owing to the randomness of positions of cells and connectivity, there were large variations of the strength of the PC response depending on the precise location of the stimulus.  ...
