However, the VAE's known failure to match the aggregate posterior often results in \emph{pockets/holes} in the latent distribution (i. e., a failure to match the prior) and/or \emph{posterior collapse}, which is associated with a loss of information in the latent space.

Here, we propose DeepSSM, a deep learning-based framework for learning the functional mapping from images to low-dimensional shape descriptors and their associated shape representations, thereby inferring statistical representation of anatomy directly from 3D images.

Learning generative shape models from grid-structured representations, aka silhouettes, is usually hindered by (1) data likelihoods with intractable marginals and posteriors, (2) high-dimensional shape spaces with limited training samples (and the associated risk of overfitting), and (3) estimation of hyperparameters relating to model complexity that often entails computationally expensive grid searches.
