Manifold learning accurately detects cardiac arrhythmias without labels

Researchers have demonstrated the effectiveness of nonlinear dimensionality reduction (NLDR) algorithms, such as UMAP and t-SNE, for unsupervised detection of cardiac arrhythmias from electrocardiogram (ECG) signals. Unlike traditional methods that focus on large variances, NLDR algorithms can identify subtle, medically relevant features without prior training or labeling. The study showed that these methods can distinguish between individuals and also separate normal heartbeats from arrhythmias within a single individual's data. This approach holds significant promise for personalized healthcare and cardiac monitoring. AI
