Non-linear Parameter Estimates from Non-stationary MEG Data

Non-linear Parameter Estimates from Non-stationary MEG Data

We demonstrate a method to estimate key electrophysiological parameters from resting state data. In this paper, we focus on the estimation of head-position parameters. The recovery of these parameters is especially challenging as they are non-linearly related to the measured field. In order to do this we use an empirical Bayesian scheme to estimate the cortical current distribution due to a ran...

Globally Optimal Parameter Estimates for Non-linear Diffusions

This paper studies an approximation method for the log likelihood function of a non-linear diffusion process using the bridge of the diffusion. The main result (Theorem 1) shows that this approximation converges uniformly to the unknown likelihood function and can therefore be used efficiently with any algorithm for sampling from the law of the bridge. We also introduce an expected maximum like...

Towards adaptive synchronization measurement of large-scale non-stationary non-linear data

Synchronization measurement of non-stationary nonlinear data is an ongoing problem in the study of complex systems, e.g., neuroscience. Existing methods are largely based on Fourier transform and wavelet transform, and there is a lack of methods capable of (1) measuring the synchronization strength of multivariate data by adapting to non-stationary, non-linear dynamics, and (2) meeting the need...
