A Massively Parallel Approach for Nonlinear Interdependency Analysis of Multivariate Signals With GPGPU

Free registration required

Executive Summary

Non-Linear Interdependency (NLI) analysis is an effective method for measurement of synchronization among brain regions, which is an important feature of normal and abnormal brain functions. But its application in practice has long been largely hampered by the ultra-high complexity of the NLI algorithms. The authors developed a massively parallel approach to address this problem. The approach has dramatically improved the run-time performance. It also enabled NLI analysis on multivariate signals which was previously impossible.
