On the Encoder-Decoder Incompatibility in Variational Text Modeling and Beyond

1 code implementation ACL 2020 Chen Wu, Prince Zizhuang Wang, William Yang Wang

To this end, we propose Coupled-VAE, which couples a VAE model with a deterministic autoencoder with the same structure and improves the encoder and decoder parameterizations via encoder weight sharing and decoder signal matching.

Neural Gaussian Copula for Variational Autoencoder

no code implementations IJCNLP 2019 Prince Zizhuang Wang, William Yang Wang

We argue that this would cause a typical training problem called posterior collapse observed in all other variational language models.

Riemannian Normalizing Flow on Variational Wasserstein Autoencoder for Text Modeling

1 code implementation NAACL 2019 Prince Zizhuang Wang, William Yang Wang

The RNF transforms a latent variable into a space that respects the geometric characteristics of input space, which makes posterior impossible to collapse to the non-informative prior.
