Connectionists: Python Package: SER model

[Fabrizio Damicelli]

Dear Connectionists,


I would like to point you to a potentially useful Python Package that might be of interest for your research, especially in the realm dynamical models and spreading dynamics on networks.

"ser": S(usceptible)E(xcited)R(efractory) model on graphs, a dynamical model of spreading excitations.
Code Repository: https://github.com/fabridamicelli/ser
As of today, a few people already trust it and the package registers >11K total downloads, ~500/month (pypi.org) and has been used already in a few research projects.

A few interesting features:
 - It is light-weight and fast (`numba` accelerated), i.e. many experiments can be simply run on a laptop
 - Installation and getting started is easy: `pip install ser`
 - Example notebooks: https://github.com/fabridamicelli/ser/blob/main/examples

The SER model is a classical cellular automaton model used to study all sorts of complex systems, ranging from forest fire dynamics to self-organized criticality in the brain.
Despite of the simplicity of its setup, it is capable of generating complex emergent dynamics with absolutely non-trivial higher-order statistical properties.
To learn more about the SER model and its applications, you might want to check out these references:

Check it out and any feedback/suggestions/bug reports are more than welcome (simply open an issue: https://github.com/fabridamicelli/ser/issues).


All the best,
Fabrizio Damicelli
