WebFeb 9, 2024 · Solution 1: Train a 5-classes classifier, when the classifier predicts the input as "label-A" or "label-B" or "label-C" or "label-D", we relabel it as "label-ABCD". Solution 2: Train a 2-classes classifier, we relabel the data as "label-ABCD" which is labeled as "label-A" or "label-B" or "label-C" or "label-D". WebOct 2, 2024 · However, when applied on real data (by taking one's ECG, computing the features and normalizing them by the same normalization value used on training and test set above), the network is always predicting: a label of 0.0 for "normal" ECGs; a label of 1.0 for noisy ECGs (which are taken as stressed ECGs).
