# Importance Weighted Autoencoders

1 Sep 2015

The variational autoencoder (VAE; Kingma, Welling (2014)) is a recently proposed generative model pairing a top-down generative network with a bottom-up recognition network which approximates posterior inference.

# Masked Autoregressive Flow for Density Estimation

By constructing a stack of autoregressive models, each modelling the random numbers of the next model in the stack, we obtain a type of normalizing flow suitable for density estimation, which we call Masked Autoregressive Flow.

# Point-Set Registration: Coherent Point Drift

15 May 2009

The goal of point set registration is to assign correspondences between two sets of points and to recover the transformation that maps one point set to the other.
