Scholar →Explainable Credit Default Prediction for Microfinance: A Gradient Boosting and SHAP Study on Consumer Credit Data
Three classifiers on 150,000 borrowers, with SHAP showing that revolving utilisation and delinquency history carry most of the signal, and all tree models calibrating poorly, a result with direct lending implications.
Compact 1D Residual Networks for Efficient 12-Lead ECG Classification: A PTB-XL Benchmarking Study
A compact 1D ResNet at 1M parameters and 4 MB matches a full-scale model on PTB-XL diagnostic superclass classification, reaching a macro AUROC of 0.9253 at 8.65 times fewer parameters, small enough for edge deployment.
Self-Supervised Early Warning of Critical Cardiorespiratory Events in Neonatal Vital-Sign Telemetry: A Pilot Feasibility Study
Self-supervised prediction of imminent desaturation from continuous neonatal telemetry, where a GRU reaches an AUROC of 0.70 to 0.96 across held-out patients with a median warning lead time of 80 seconds.
