This is the official code repository accompanying the paper titled Toward Robust Automated Cardiovascular Arrhythmia Detection using Self-supervised Learning and 1-Dimensional Vision Transformers.

Abstract

This project developed a robust automated cardiovascular arrhythmia detection system using self-supervised pretraining and 1D vision transformer architectures tailored for ECG signals. The system emphasizes reliability under distribution shift and low-labeled-data regimes.

Dataset & Artifacts

Methods

  • Self-supervised pretraining on large unlabeled ECG corpora
  • 1D Vision Transformer fine-tuning for classification and detection
  • Augmentation strategies, calibration, and uncertainty estimation for safer clinical deployment

Results

  • Achieved state-of-the-art robustness across held-out datasets.
  • Demonstrated improved calibration and lower false positive rates in low-label settings.

Relevance

This work underpins my research focus on medical AI and time-series modelling, and complements my engineering work on large-scale retrieval systems by bringing rigorous evaluation and robustness-first design.
