We propose a new algorithm to impose independence constraints based on second order statistics in one mode of the Parallel Factor Analysis / Canonical Decomposition, also known as the CP model, and show with simulations that it outperforms in some cases the ordinary CP model.
When patients with epilepsy cannot be helped with medication, they stay one week in an epilepsy monitoring unit in order to localise the part of the brain that is causing the seizures. The electroencephalogram (EEG) is then recorded over several days as it is the direct measurement of electrical brain activity. We developed a method to extract localising information out of the EEG, even at low signal-to-noise...
Long-term electroencephalographic (EEG) recordings are important in the presurgical evaluation of refractory partial epilepsy for the delineation of the ictal onset zones. In this paper we introduce a new concept for an automatic, fast and objective localisation of the ictal onset zone in ictal EEG recordings and show with a simulation study that canonical decomposition of ictal scalp EEG allows a...
