Description
I will introduce a procedure to infer the fields and the
couplings of a
spatially-distributed Ising model, given the magnetizations and
pairwise correlations of spins. The algorithm is based on the
recursive decomposition of the entropy into contributions
coming from
clusters of spins. I will explain and validate the
procedure on synthetic
data sets,and then apply it to experimental data coming from
multi-electrode recordings of neural activity.
