How do generative AI models differ from traditional discriminative models in healthcare applications?

generative AI models learn the undetlying distribution of data and can create new, synthetic data instances. Traditional Discriminative Models focus on classifying or interpreting existing data but cannot create new data.

For the article 1 (Exploring the potential of generative artificial intelligence in medicial image synthesis: opportunuties, challenges, and future directions) page 1 of introdution specify that "creation of derivative synthetic darasets." page 2 specify that "capable of creating content." and "creation of realistic medical images (synthetic data)"

What is meant by the term “model as a dataset”?

For the article 1 (Exploring the potential of generative artificial intelligence in medicial image synthesis: opportunuties, challenges, and future directions) page 2, lines 2-4, colomn 1 "The advancement of generative artificial intelligence introduces a new concept in data sharing, which we refer to as a model as a dataset. In this concept, generative models learn and store patterns and characteristics of the original data in their internal parameters (weights)." and These trained weights contain a compressed version of the key features and relationships of the training data. Unlike traditional dataset sharing, which involves transferring actual images, sharing model weights provides an efficient alternative that allows others to generate new synthetic images with properties similar to the original data."

What is one major ethical concern associated with generative AI in medical imaging?

For article 1 (page 7-8) : "Although synthetic datasets can help to preserve patient privacy by generating anonymised data, concerns regarding potential data copying still exist. If a generative model is trained on a specific dataset and can replicate images that closely resemble the original data, then the model might inadvertently reveal sensitive patient information."
