Abstract
Abstract Epilepsy is one of the most common neonatal neurological disorders, causing significant nervous system dysfunction. Early detection of seizures is critical for timely clinical intervention and reducing long-term neurological consequences. This study proposes an automated framework utilizing deep transfer learning architectures to classify neonatal seizures using topographic brainpower maps extracted from EEG signals. We utilized a publicly accessible dataset comprising recordings from 79 newborns, analyzed across three temporal window scenarios (1, 5, and 8 s). Three deep transfer learning models, GoogLeNet, ResNet-18, and ShuffleNet, were rigorously evaluated. While initial results approached the optimal accuracy across all temporal windows, a more rigorous subject-wise protocol was implemented to ensure clinical generalizability, where the models were tested on entirely unseen patients. Under this strict validation, ResNet-18 emerged as the superior architecture, achieving a remarkable peak subject-wise accuracy of 97.1% in the 8-second window scenario. Our findings confirm that the proposed framework is highly robust against inter-patient variability, representing a reliable and methodologically sound strategy for automated neonatal intensive care monitoring.
