BioFormer: Rethinking Cross-Subject Generalization via Spectral Structural Alignment in Biomedical Time-Series
arXiv:2605.22468v1 Announce Type: new Abstract: Cross-subject generalization in biomedical time-series refers to training on data from some subjects and testing on unseen subjects.The key challenge is to suppress subject specific variability in BTS representations.Most existing methods implicitly suppress the variability through model building or subject adversarial learning, but rarely model it explicitly.We introduce spectral drift as a new perspective to characterize subject specific variability.Specifically, BTS signals under the same label often share consistent oscillatory structure, yet
The paper addresses a critical challenge in biomedical AI—generalizing models across different subjects—which is a prerequisite for widespread clinical adoption of AI in healthcare.
Improving cross-subject generalization enables more robust and reliable AI diagnostics and monitoring tools, accelerating the deployment of AI in personalized medicine and health monitoring.
This research introduces a novel method to explicitly model and suppress subject-specific variability in biomedical time-series, potentially leading to more accurate and widely applicable AI-driven health solutions.
