Beat-Synchronous Tokenization for ECG Transformers
Ahmed Sameh, Nolan Wilson, Max Enderlein +1
Transformer-based electrocardiogram (ECG) models commonly tokenize waveforms into fixed temporal patches. Though convenient, fixed patching can split heartbeat structures across to…
The Impact of Temporal Context Length and Encoding Strategies on Self-Supervised ECG Representation Learning
Ahmed Sameh, Ramzi Al-Sharawi, Yogatheesan Varatharajah
Self-supervised electrocardiogram (ECG) models are often trained on a few seconds of ECG signal and, increasingly, on discretized token sequences. It remains unclear whether these…
Improving Out-of-distribution Human Activity Recognition via IMU-Video Cross-modal Representation Learning
Seyyed Saeid Cheshmi, Buyao Lyu, Thomas Lisko +3
Human Activity Recognition (HAR) based on wearable inertial sensors plays a critical role in remote health monitoring. In patients with movement disorders, the ability to detect ab…
