Generative AI - Variational Autoencoders (VAEs)

Variational Autoencoders (VAEs)

Kingma and Welling proposed variational autoencoders in 2013. Neural networks and probabilistic modeling components are combined in VAEs, a kind of generative model. As opposed to conventional autoencoders, vector autoencoders (VAEs) map input data to a latent space probability distribution, which enables them to sample from this distribution to produce new data.

How VAEs Work

VAEs are made up of two primary parts:

  • Encoder: This network represents the input data as a probability distribution by compressing it into a latent space.
  • Decoder: Using the latent space distribution, this network recreates the data.

The regularization component that is added to the loss function, which guarantees that the latent space has a known distribution (often a Gaussian), is the main novelty of vector approximation techniques (VAEs). By sampling from the latent space, VAEs are able to produce fresh data thanks to this regularization.

Use Cases

Applications requiring data production and reconstruction benefit greatly from VAEs. Among the noteworthy use cases are:

  • Image Generation: VAEs are excellent for tasks like image synthesis and data augmentation because they can create new pictures by sampling from the latent space.
  • Anomaly Detection: By calculating the degree to which data deviates from the predicted distribution, VAEs trained on the normal distribution of the data can detect abnormalities.
  • Data Compression: VAEs are helpful for applications like picture compression and denoising because they can compress data into a lower-dimensional latent space.
