Overcoming Data Scarcity in Neonatal Respiratory Monitoring
The study addresses the critical lack of real-time clinical data by proposing a novel synthetic signal generation framework. This framework replicates infant respiratory cycles with high physiological fidelity, simulating both normal and pathological breathing patterns such as apnea, hypoxia, and periodic breathing. The inclusion of Gaussian noise and exponential functions ensures biological realism, providing a robust dataset for training machine learning models.

Superior Detection of Respiratory Anomalies with CNN-BiLSTM
A comprehensive feature extraction pipeline, encompassing both time- and frequency-domain characteristics, was developed to prepare the synthetic data. This data was then used to train and evaluate Convolutional Neural Networks (CNNs), CNN-BiLSTM models, and Random Forests. The CNN-BiLSTM model demonstrated superior performance, achieving the highest classification accuracy of 96.16%, significantly outperforming standalone CNN (93.0%) and Random Forest (92.03%) models. This highlights the effectiveness of combining convolutional layers for local feature extraction with BiLSTM layers for capturing temporal dependencies in sequential data.
