Patient-specific multivariate waveform detector for epileptic seizure detection

Intracranial EEG recordings of epilepsy patients consist of numerous channels, which can be highly correlated due to their spatial proximity. We propose a vector-autoregressive (VAR)-based multivariate waveform detector (MWD), which is able to exploit inter-channel correlations for the detection of patient-specific waveforms. The technical novelty is to design the MWD patient-individually and to process several channels simultaneously. Here, the MWD is used for epileptic seizure detection. We analyzed typical waveforms appearing in seizures of 2 patients suffering from pharmacoresistant focal epilepsy. They unde…
