Researchers have developed a novel method called \"ours\" for deploying AI models in multi-source Electrocardiogram (ECG) scenarios where raw data from earlier sources cannot be retained. This approach freezes a pretrained backbone and assigns each new data source an isolated classifier, preventing interference. A lightweight router is trained on retained features and domain labels to select the appropriate expert, with a validation-calibrated margin rule fusing the top two most likely experts. While source-aware expert selection achieved a Macro-F1 score of 0.7915 on several datasets, autonomous source inference without IDs remained the primary bottleneck, with a small gain observed from the proposed fusion method over standard MLP routing.
