Researchers have developed a novel Manifold-Informed Neural Network (MINN) that can infer electrolyte levels from electrocardiogram (ECG) data, even with limited labeled samples. Unlike traditional physics-informed neural networks, MINN utilizes a manifold operator residual derived from a learned latent space graph, allowing it to handle problems where explicit physical operators are unknown. In evaluations using the MIMIC-IV-ECG dataset, MINN demonstrated superior performance in classifying potassium, calcium, and magnesium levels, achieving a Macro-F1 score of 0.61 for potassium and showing significant gains with as little as 1% labeled data.
