A comprehensive evaluation of pretraining strategies for channel-agnostic contrastive self-supervision of biosignals
arXiv:2410.19842v2 Announce Type: replace-cross Abstract: Contrastive learning yields impressive results for self-supervision in computer vision. The approach relies on the creation of positive pairs, something which is often achieved through augmentations. However, for multivariate time series effective augmentations can be difficult to design. Additionally, the number of input channels for biosignal datasets often varies from application to application, limiting the usefulness of large self-supervised models trained with specific channel configurations. Motivated by these challenges, we set
The proliferation of biosignal data across diverse applications necessitates more robust and adaptable self-supervision techniques, driving current research in AI for health and biometric analysis.
Developing channel-agnostic pretraining for biosignals addresses a significant limitation in applying large AI models to real-world, variable biomedical data, opening new avenues for medical diagnostics and monitoring.
This research potentially makes AI models trained on biosignals more versatile and less dependent on specific sensor configurations, accelerating deployment in varied healthcare and biometric contexts.
