The Nonlinear Statistics of High-Contrast Patches in Natural Images
(Springer Verlag, 2003)Recently, there has been a great deal of interest in modeling the non-Gaussian structures of natural images. However, despite the many advances in the direction of sparse coding and multi-resolution analysis, the full ... -
A Rate-Independent Measure of Irregularity for Event Series and It's Application to Neural Spiking Activity
(IEEE, 2008)Although higher-order statistics of neuronal firing have been characterized in neuroscience, many analyses ignore the nonstationarity of the background firing rate. We discuss how to measure the irregularity of interspike ...
