Variational Autoencoder (VAE)

VAE is a type of generative model that uses deep learning to generate new data samples. It works by learning a latent representation of the input data, which can then be used to generate new data samples that are similar to the input data. VAEs are commonly used in medical image analysis, drug discovery, and personalized medicine.

Generative Adversarial Networks (GANs)

GANs are another type of generative model that works by learning the distribution of the input data and generating new data samples that are similar to the input data. GANs work by training two neural networks – a generator network that generates new data samples and a discriminator network that distinguishes between the generated data and the real data. GANs are commonly used in medical image analysis and drug discovery.

Autoregressive Models

Autoregressive models are a type of generative model that works by predicting the next value in a sequence based on the previous values. They work by learning the conditional probability distribution of the input data and generating new data samples by sampling from this distribution. Autoregressive models are commonly used in electronic health record analysis, disease diagnosis, and personalized medicine.
