Inference Methods for Interaction and Noise Intensities Using Only Spike-time Data on Coupled Oscillators
We propose theoretical methods to infer coupling strength and noise intensity

simultaneously through an observation of spike timing in two well-synchronized

noisy oscillators. A phase oscillator model is applied to derive formulae

relating each of the parameters to some statistics from spike-time data. Using

these formulae, each parameter is inferred from a specific set of statistics.

We demonstrate the methods with the FitzHugh-Nagumo model as well as the phase

model. Our methods do not require any external perturbation and thus are ready

for application to various experimental systems..
