Title:
Non-parametric estimation of linear filters for point processes

Abstract:
A main challenge in neuron science is to model the dynamic activity of the brain and how it responds to external stimuli. We present models of neuron network activity based on multichannel spike data. The models form a class of point orocess models with spike rates determined through linear filters of the spike histories. The filters are given in terms of filter functions that are estimated non-parametrically as elements in e.g. a reproducing kernel Hilbert space. We discuss how the models can be used to infer network connectivity and predictions of stimuli (intervention) effects. The methods used are available via the R package ppstat.
