    I still code in R for most of the time, so I walk through the R code in the deep learning with R book.
      
    
   
  
  
    
    
      
      Imagine you have a bunch of pictures of cats, and you want to find a way to generate new cat pictures that look similar to the ones you have. A variation autoencoder (VAE) is like a magical tool for creating these new cat pictures.
Here’s how it works:
Encoder: The VAE first takes your cat pictures and passes them through an encoder. This encoder is like a detective that tries to capture the important features of the cats, such as their fur color, size, and shape.
