Frequently Asked Questions

What is self-supervised learning?

It is a machine learning approach that learns representations from unlabeled data by solving pretext tasks such as predicting missing parts of an image

How does USF-MAE differ from MoCo v3?

USF-MAE uses masked autoencoding tailored to ultrasound, while MoCo v3 relies on contrastive learning between augmented views

Will these models be used in clinical practice?

They require further validation and regulatory approval before being deployed in routine clinical workflows
