A simple deep generative model library in Theano and Lasagne

Primary LanguagePython

Tars

Build Status Codacy Badge

Tars is the deep generative models library. It has the following features:

  • Various distributions

    • Gaussian, Bernoulli, Laplace, Gamma, Beta, Dirichlet, Bernoulli, Categorical, and so on.
    • We can draw samples from these distributions by the reparameterization trick .

  • Various models

    • Autoencoder
    • VAE
      • Conditional VAE
      • Importance weighted autoencoder
      • JMVAE
      • Multiple latent layers
    • GAN, Conditional GAN
    • VAE-GAN, conditional VAE-GAN
    • VAE-RNN
      • Variational RNN
      • DRAW, Convolutional DRAW
    • Various lower bounds
      • The evidence lower bound (ELBO, which is the same as the original lower bound)
      • The importance sampling lower bound
      • The variational R'enyi bound

  • Note: Some of the implementations of the above models have not yet been released in this version. If you want to use such models, please use the old version (v0.0.2).

  • For a more detailed explanation of this library, please refer to this page (in Japanese).
