Overview
This project is about estimating causal states from population time series data and reconstruction of $\epsilon$-machines. One interesting question would be to look at the causal states and find some correlations to nodes in a dynamic food web. Another question would be to quantify the population dynamics.
We have have a frequentist [1] and a Bayesian [2] reconstruction algorithm. It would be interesting to see if they come up with the same result. As input data we can use a food web simulation we have seen in Neos lecture, wich is available [here].
