Summary
This study introduces PLE-TabM, a novel deep learning model for cardiotocography (CTG) classification. The model achieves high accuracy in fetal health assessment, offering an objective tool for obstetricians.
Area of Science:
- Medical Technology
- Artificial Intelligence in Healthcare
- Fetal Monitoring
Background:
- Cardiotocography (CTG) classification aids obstetricians in fetal health assessment.
- Manual interpretation of CTG data suffers from subjectivity.
- Deep learning models struggle with tabular data representation.
Purpose of the Study:
- To develop an objective and accurate method for fetal health status classification using CTG data.
- To address the limitations of traditional methods and deep learning on tabular data.
Main Methods:
- Proposed PLE-TabM, a tabular deep learning model integrating Piecewise Linear Encoding (PLE) and efficient weight integration.
- Utilized a public CTG dataset for model training and evaluation.
- Employed Gradient SHapley Additive exPlanations (Gradient SHAP) for feature importance analysis.
Main Results:
- PLE-TabM achieved 95.77% accuracy and 93.83% macro F1 score in fetal health classification.
- The model outperformed traditional machine learning methods.
- Feature importance analysis provided insights into classification drivers.
Conclusions:
- PLE-TabM offers a reliable and objective tool for CTG classification.
- The study combines efficient tabular learning with interpretability for clinical decision support.
- The algorithm was successfully validated on clinical patient data.
