L Regularization for Reconstruction of a non-equilibrium Ising Model
Hong-Li Zeng, John Hertz, Yasser Roudi
The couplings in a sparse asymmetric, asynchronous Ising network are reconstructed using an exact learning algorithm. L regularization is used to remove the spurious weak conne…
Maximum likelihood reconstruction for Ising models with asynchronous updates
Hong-Li Zeng, Mikko Alava, Erik Aurell +2
We describe how the couplings in an asynchronous kinetic Ising model can be inferred. We consider two cases, one in which we know both the spin history and the update times and one…
The Effect of Nonstationarity on Models Inferred from Neural Data
Joanna Tyrcha, Yasser Roudi, Matteo Marsili +1
Neurons subject to a common non-stationary input may exhibit a correlated firing behavior. Correlations in the statistics of neural spike trains also arise as the effect of interac…
