Random Forest classifier for EEG-based seizure prediction
This work addresses seizure prediction for epilepsy patients, presenting an incremental improvement over existing methods.
The paper tackles epileptic seizure prediction using a Random Forest classifier, achieving a sensitivity of 82.07% and a false positive rate of 0.0799/h on the CHB-MIT dataset.
Epileptic seizure prediction has gained considerable interest in the computational Epilepsy research community. This paper presents a Machine Learning based method for epileptic seizure prediction which outperforms state-of-the art methods. We compute a probability for a given epoch, of being pre-ictal against interictal using the Random Forest classifier and introduce new concepts to enhance the robustness of the algorithm to false alarms. We assessed our method on 20 patients of the benchmark scalp EEG CHB-MIT dataset for a seizure prediction horizon (SPH) of 5 minutes and a seizure occurrence period (SOP) of 30 minutes. Our approach achieves a sensitivity of 82.07 % and a low false positive rate (FPR) of 0.0799 /h. We also tested our approach on intracranial EEG recordings.
