Medical Knowledge-Guided Semi-Supervised Bi-Ventricular Segmentation

Pseudo-labeling is a well-studied semi-supervised learning approach that generates artificial labels for unlabeled data based on the predictions of an initial model trained on labeled data. Although pseudo-labeling is an effective approach for a wide range of tasks, incorporating physical knowledge concentrated on a particular organ (such as cardiac structures), can outperform the general strategy employed in pseudo-labeling. In this work, we …
