Symbolic Transfer Entropy

My implementation of Symbolic Transfer Entropy -- a method of estimating transfer entropy which was proposed in

Symbolic Transfer Entropy

Files

In the order of which they were used:

1. coupled_lorenz.m
   • integrates coupled lorenz systems and stores time series data in lorenz_data/ (too big; not included in repository)
   • each saved file corresponds to one simulation (i.e. one initial condition)
     • each pair of columns corresponds to one coupling parameter
     • odd columns correspond to driver (x), even columns correspond to response (y)
2. coupled_rossler.m
   • same as coupled_lorenz.m but with rossler systems
3. symbolic_TE.py
   • my implementation of Symbolic Transfer Entropy (STE)
4. TE_test.py
   • computes STE for lorenz system and rossler system
   • stores entropies in lorenz_entropies.csv and rossler_entropies.csv
5. TE_plot.py
   • recreates figures from paper
   • resulting figures are saved in figs/
